Abstract

A display device includes a display panel including a non-driven area and a driven area symmetric relative to a first straight line passing on the figure center of the driven area and a covering portion covering a peripheral portion of the display panel and including an opening portion symmetric relative to a second straight line passing on the figure center of the opening portion. When the first straight line and the second straight line are viewed from a first direction side, the first straight line and the second straight line are disposed in parallel to each other on a plane, and when the plane is viewed in a plan view, one side portion and the other side portion that are included in the driven area and covered by the covering portion and that are located opposite each other with the first straight line located between the one side portion and the other side portion have mutually different lengths in a direction perpendicular to the first straight line.

Claims (15)

1. A display device comprising:

a display panel including a non-driven area and a driven area and that is symmetric relative to a first straight line passing through a figure center of the driven area; and

a covering portion covering a peripheral portion of the display panel and including an opening portion and that is symmetric relative to a second straight line passing through a figure center of the opening portion,

wherein,

when the first straight line and the second straight line are viewed from a first direction side, the first straight line and the second straight line are disposed in parallel to each other on a plane, and

when the plane is viewed in a plan view, a first side portion of the driven area and a second side portion of the driven area that are covered by the covering portion and that are located opposite each other with respect to the first straight line have different lengths in a direction perpendicular to the first straight line.

2. The display device according to claim 1 , wherein the display panel further includes a first substrate on which a plurality of pixel electrodes are disposed, a second substrate on which a facing electrode facing the plurality of pixel electrodes is disposed, and a plurality of image formation portions each including a dispersion liquid disposed between the first substrate and the second substrate and including particles and a dispersion medium, each of the plurality of image formation portions being configured to form a display image in accordance with an electric potential difference between the facing electrode and a corresponding one of the plurality of pixel electrodes.

3. The display device according to claim 2 further comprising:

a light source; and

a light guiding member disposed at a second substrate side opposite the first substrate and configured to guide light from the light source.

4. The display device according to claim 1 , wherein the driven area and the opening portion have mutually similar shapes.

5. A display device comprising:

a display panel including a non-driven area and a driven area and that is symmetric relative to a first straight line passing through a figure center of the driven area; and

a covering portion that covers a peripheral portion of the display panel and that includes an opening portion, the covering portion being symmetric relative to a second straight line that passes through a figure center of the opening portion,

wherein the figure center of the display panel is offset from the figure center of the opening portion such that the covering portion covers the driven area on a first side of the first straight line by a greater distance than the covering portion covers the driven area on a second side of the first straight line.
