Abstract

An electrooptic device includes: a display panel; an adhesive layer mounted on the outer surface of the display panel; and a functional member bonded to the display panel with the adhesive layer. The adhesive layer has spacers dispersed on the functional member or the display panel.

Claims

1. An electrooptic device comprising:

a display panel;

an adhesive layer mounted on the outer surface of the display panel; and

a functional member bonded to the display panel with the adhesive layer, wherein

the adhesive layer has spacers dispersed on the functional member or the display panel.

2. The electrooptic device according to claim 1, wherein the spacer is 50 μ

m or less in size in the direction from the display panel to the functional member.

3. The electrooptic device according to claim 1, wherein the spacer is shaped like a ball.

4. The electrooptic device according to claim 1, wherein the spacer is shaped like a fiber.

5. The electrooptic device according to claim 1, wherein the adhesive layer and the spacers are transparent.

6. An electronic device comprising the electrooptic device according to claim 1.

7. A method for manufacturing an electrooptic device, the method comprising:

manufacturing a display panel;

applying an adhesive mixed with a plurality of spacers onto the surface of one of the functional member and the display panel; and

bonding the functional member to the display panel.

8. A method for manufacturing an electrooptic device, the method comprising:

manufacturing a display panel;

dispersing a plurality of spacers onto the surface of one of the functional member and the display panel;

fixing the position of the plurality of spacers dispersed;

applying an adhesive onto the surface of one of the functional member and the display panel; and

bonding the functional member to the display panel.
