Abstract

A display device includes a display panel in which a display screen and an indicator region are two-dimensionally arranged, an indicator substrate which is mounted with a light source component and which is arranged on a back face side of the display panel so as to face the indicator region but not to face the display screen, and a control substrate which is a separate part from the indicator substrate and on which a control circuit for the display screen is formed. The control substrate is arranged on the back face side of the display panel and arranged distant from the display panel than the indicator substrate, and the control substrate is arranged so as not to face at least a portion of each of the display screen and the indicator substrate.

First claim

What is claimed is:

1. A display device comprising:
a display panel in which a display screen and an indicator region are two-dimensionally arranged;
an indicator substrate mounted with a light source component, the indicator substrate being arranged on a back face side of the display panel so as to face the indicator region but not to face the display screen; and
a control substrate which is a separate part from the indicator substrate and on which a control circuit for the display screen is formed, the control substrate being arranged on the back face side of the display panel and arranged distant from the display panel than the indicator substrate, and the control substrate being arranged so as not to face at least a portion of each of the display screen and the indicator substrate.

2. The display device according to claim 1 , wherein
the display panel is configured to be installed in an upright position in which the display panel is arranged to stand on a predetermined installation place,
the indicator region of the display panel is disposed at a position shifted from the display screen in a right-left direction with respect to the upright position, and
with respect to an up-down direction with respect to the upright position, the control substrate is arranged so as not to face a portion on an upper end side of each of the display screen and the indicator substrate.

3. The display device according to claim 1 , wherein
the display panel is configured to be installed in an upright position in which the display panel is arranged to stand on a predetermined installation place, and
with respect to an up-down direction with respect to the upright position, the control substrate is arranged below the indicator substrate and arranged along an intersecting direction with respect to the indicator substrate such that the control substrate is entirely not facing each of the display screen and the indicator substrate.

4. The display device according to claim 1 , wherein the indicator substrate and the control substrate are connected to each other via connector connection.

5. The display device according to claim 1 , further comprising a device housing that, together with the display panel, defines an accommodating space for the indicator substrate and the control substrate.

6. The display device according to claim 1 , further comprising:
a first device housing that, together with the display panel, defines a first accommodating space for accommodating the indicator substrate; and
a second device housing arranged on a back side of the first device housing corresponding to the back face side of the display panel, the second device housing defining a second accommodating space for accommodating the control substrate.

7. The display device according to claim 6 , further comprising a connecting cable that electrically connects the display screen of the display panel defining the first accommodating space and the control substrate accommodated in the second accommodating space.

8. The display device according to claim 1 , wherein
the indicator region on the display panel includes a diffusing portion that passes light from the light source component while diffusing it and a blocking portion that surrounds the diffusing portion to block light, and
the diffusing portion and the blocking portion are integrally formed by two-color molding.
