Abstract

According to an aspect, a display device includes a first substrate, a second substrate, and light shielding layer. The first substrate is a plate-like member and is provided with a switching element for each of pixels arranged in a matrix and a wiring coupled to the switching element. The second substrate is a plate-like member facing the first substrate and having a smaller thickness than the thickness of the first substrate. The second substrate has an outer edge that faces a portion of the first substrate to which the wiring is not led out and that is positioned inside an outer edge of the first substrate when viewed from a direction orthogonal to a substrate surface of the first substrate.

First claim

What is claimed is:

1. A display device comprising:
a first substrate that is a plate-like member and is provided with a switching element for each of pixels arranged in a matrix and a wiring coupled to the switching element;
a second substrate that is a plate-like member facing the first substrate and having a smaller thickness than the thickness of the first substrate, the second substrate having an outer edge that faces a portion of the first substrate to which the wiring is not led out and that is positioned inside an outer edge of the first substrate when viewed from a direction orthogonal to a substrate surface of the first substrate; and
a light shielding layer that is provided to a surface of the second substrate opposite to the first substrate and that divides an image displayed by the pixels by blocking a part of light from the second substrate.

2. The display device according to claim 1 , further comprising:
a sealing member arranged between the first substrate and the second substrate and on a periphery of the first substrate and the second substrate, wherein
a distance from the sealing member to the outer edge of the second substrate is larger than a distance from the outer edge of the second substrate to the outer edge of the first substrate at the portion of the first substrate to which the wiring is not led out.

3. The display device according to claim 1 , wherein the thickness of the second substrate is one-twentieth to one-fifth of the thickness of the first substrate.

4. An electronic apparatus comprising the display device according to claim 1 .

5. A method for manufacturing a display device, the method comprising:
forming cuts for separating a plurality of display panel units from a display panel group in which the display panel units are formed on a first substrate and a second substrate facing the first substrate and having a thickness of one-twentieth to one-fifth of the thickness of the first substrate; and
dividing the display panel group along the first and the second cuts, wherein
the forming cuts includes
forming first cuts at two positions sandwiching a position corresponding to an outer edge of the display panel on a surface of the second substrate, and
forming a second cut between the first cuts adjacent to each other on a surface of the first substrate in plan view.
