Abstract

Provided is a configuration of a display device that can have a narrower frame. A display device ( 1 ) includes a first display unit ( 11 ) including a first substrate ( 111 ); a second display unit ( 12 ) including a second substrate ( 121 ) that is arranged so as to be adjacent to the first substrate ( 111 ) in an in-plane direction of the first substrate ( 111 ); a first line group ( 1171 ) that supplies a signal to the first display unit ( 11 ), the first line group ( 1171 ) passing through between the first substrate ( 111 ) and the second substrate ( 121 ); and a second line group ( 1271 ) that supplies a signal to the second display unit ( 12 ), the second line group ( 1271 ) passing through between the first substrate ( 111 ) and the second substrate ( 121 ). The first display unit ( 11 ) includes a mounting area to which the first line group ( 1171 ) is connected, in a part that is opposed to the second display unit ( 12 ), and the second display unit ( 12 ) includes a mounting area to which the second line group ( 1271 ) is connected, in a part that is opposed to the first display unit ( 11 ).

First claim

1 . A display device comprising:
a first display unit including a first substrate; a second display unit including a second substrate that is arranged so as to be adjacent to the first substrate in an in-plane direction of the first substrate; a first line group that supplies a signal to the first display unit, the first line group passing through between the first substrate and the second substrate; and a second line group that supplies a signal to the second display unit, the second line group passing through between the first substrate and the second substrate, wherein the first display unit includes a mounting area to which the first line group is connected, in a part that is opposed to the second display unit, and the second display unit includes a mounting area to which the second line group is connected, in a part that is opposed to the first display unit.

2 . The display device according to claim 1 , further comprising:
a translucent front panel that is arranged on a viewer side with respect to the first display unit and the second display unit, so as to cover the first display unit and the second display unit.

3 . The display device according to claim 2 , further comprising:
a colored section that is formed on the front panel, the colored section being formed between a display area of the first display unit and a display area of the second display unit, when viewed in a plan view.

4 . The display device according to claim 1 , further comprising:
a first flexible substrate on which the first line group is formed; and a second flexible substrate on which the second line group is formed, wherein the first substrate includes a straight-line portion along an outline thereof, the first flexible substrate is arranged along an edge of the first substrate that includes the straight-line portion, the second substrate includes a straight-line portion along an outline thereof, and the second flexible substrate is arranged along an edge of the second substrate that includes the straight-line portion.

5 . The display device according to claim 4 ,
wherein the first flexible substrate is connected to the first substrate, and the second flexible substrate is connected to the second substrate.

6 . The display device according to claim 5 ,
wherein the first flexible substrate is arranged so as to intersect with a virtual line obtained by extending a line along the straight-line portion of the second substrate, and the second flexible substrate is arranged so as to intersect with a virtual line obtained by extending a line along the straight-line portion of the first substrate.

7 . The display device according to claim 4 ,
wherein the first display unit further includes a first counter substrate that is arranged on a viewer side with respect to the first substrate, so as to be opposed to the first substrate, the second display unit further includes a second counter substrate that is arranged on a viewer side with respect to the second substrate, so as to be opposed to the second substrate, the first flexible substrate is connected to the first substrate, and the second flexible substrate is connected to the second counter substrate.

8 . The display device according to claim 7 ,
wherein the first flexible substrate and the first substrate are connected with each other by a first connection member, the second flexible substrate and the second counter substrate are connected with each other by a second connection member, and the following expression is satisfied:
t _ A 2≧ t _ B 2+ t _ FPC× 2+ t _ ACF× 2

where “t_A2” represents a thickness of the first counter substrate, “t_B2” represents a thickness of the second counter substrate, “t_FPC” represents each thickness of the first flexible substrate and the second flexible substrate, and “t_ACF” represents each thickness of the first connection member and the second connection member.

9 . The display device according to claim 1 , further comprising:
a common substrate that is arranged on a viewer side with respect to the first substrate and the second substrate, so as to be opposed to the first substrate and the second substrate.

10 . The display device according to claim 9 , further comprising:
a common flexible substrate on which the first line group and the second line group are formed, the common flexible substrate being connected to the common substrate.

11 . The display device according to claim 1 ,
wherein the display device has a circular or oval outer shape in plan view.

12 . The display device according to claim 1 , further comprising:
a control circuit that supplies a signal to the first line group and the second line group, wherein the control circuit is configured to cause a continuous image to be displayed on the first display unit and the second display unit.

13 . An apparatus comprising the display device according to claim 1 .
