Abstract

A flat portion includes a corner side that is provided between the first and second sides and of which a tangent intersects the first and second sides. An inclined portion includes a first portion that is bent along the first side, a second portion that is bent along the second side, and a third portion that is bent from the corner side. A flexible display panel includes a notch that is provided between the first and second portions and of which a gap spreads in a direction away from the flat portion in a state where the flexible display panel is laid flat. Facing sides of the notch facing each other are adjacent to each other in a state where the flexible display panel is bent.

First claim

the flat portion includes a first side that extends in a first direction, a second side that extends in a second direction intersecting the first direction, and a corner side that is provided between the first side and the second side and of which a tangent intersects both the first side and the second side,
the inclined portion includes a first portion that is bent along the first side, a second portion that is bent along the second side, and a third portion that is bent from the corner side,
the flexible display panel includes a notch that is provided between the first portion and the second portion and of which a gap spreads in a direction away from the flat portion in a state that the flexible display panel is laid flat, and
facing sides of the notch facing each other are adjacent to each other in a state that the flexible display panel is bent,
further comprising:
a first scanning circuit that is provided in the first portion;
a second scanning circuit that is provided in the second portion;
a third scanning circuit that is provided in the third portion;
a plurality of first scanning lines that are drawn out from the first scanning circuit in the first direction and are provided in the first portion;
a plurality of second scanning lines that are drawn out from the second scanning circuit in a direction intersecting the second direction and are continuously provided in the second portion and the flat portion to extend in the first direction at least in the flat portion;
a plurality of third scanning lines that are drawn out from the third scanning circuit and are provided in the third portion, and
a control wiring that passes through the first scanning circuit, the second scanning circuit, and the third scanning circuit,
wherein the control wiring includes a portion that extends along the facing sides of the notch.

2. The display device according to claim 1 ,
wherein in the flat portion, the second side is provided on each of both sides of the first side.

3. The display device according to claim 1 ,
wherein the notch has a V-shape in which an inner corner has an acute angle.

4. The display device according to claim 1 ,
wherein the corner side has an arc shape.

5. The display device according to claim 1 ,
wherein the flexible display panel includes a substrate, a plurality of pixel electrodes that are provided on the substrate, a common electrode that faces the pixel electrodes, and a contact electrode that is provided on the substrate to be connected to the common electrode, and
the contact electrode includes the facing sides of the notch and is continuously provided along an outer edge of the inclined portion.

6. The display device according to claim 1 ,
wherein the flexible display panel includes the notch that is provided between the first portion and the third portion, and
the second portion and the third portion are continuously integrated.

7. The display device according to claim 6 , further comprising a plurality of signal lines,
wherein the signal lines include a first group of signal lines that continuously pass through the flat portion and the first portion and a second group of signal lines that continuously pass through the second portion and the third portion.

8. The display device according to claim 7 ,
wherein in the third portion, the second group of signal lines extend along a concentric circle having a center on the flat portion side.

9. The display device according to claim 1 ,
wherein the flexible display panel includes the notch that is provided between the second portion and the third portion, and
the first portion and the third portion are continuously integrated.

10. The display device according to claim 9 , further comprising a plurality of signal lines,
the signal lines include a group of signal lines that passes through the second portion, the flat portion, and the third portion.

11. A display device comprising:
a flexible display panel that includes a display area on which an image is displayed,

the flexible display panel includes a flat portion that includes the main display area and an inclined portion that extends to be bent and inclined from the flat portion and includes the sub-display area,
the flat portion includes a first side that extends in a first direction, a second side that extends in a second direction intersecting the first direction, and a corner side that is provided between the first side and the second side and of which a tangent intersects both the first side and the second side,
the inclined portion includes a first portion that is bent along the first side, a second portion that is bent along the second side, and a third portion that is bent from the corner side,
the flexible display panel includes a notch that is provided between the first portion and the second portion and of which a gap spreads in a direction away from the flat portion in a state that the flexible display panel is laid flat, and
facing sides of the notch facing each other are adjacent to each other in a state that the flexible display panel is bent,
further comprising:
a first scanning circuit that is provided in the first portion;
a second scanning circuit that is provided in the second portion;
a third scanning circuit that is provided in the third portion;
a plurality of first scanning lines that are drawn out from the first scanning circuit in the first direction and are provided in the first portion;
a plurality of second scanning lines that are drawn out from the second scanning circuit in a direction intersecting the second direction and are continuously provided in the second portion and the flat portion to extend in the first direction at least in the flat portion; and
a plurality of third scanning lines that are drawn out from the third scanning circuit and are provided in the third portion,
wherein the first scanning circuit is present at an end portion of the first portion in the first direction,
the second scanning circuit is present at an end portion of the second portion opposite to the flat portion, and
the third scanning circuit is present at an end portion of the third portion opposite to the flat portion.
