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 polarizer bonded directly to the display panel with the adhesive layer, wherein

the adhesive layer has spacers dispersed therein that each directly contact the polarizer and the display panel such that a distance between the polarizer and the display panel is uniform along an entire length of an interface therebetween, wherein the adhesive layer and the spacers are transparent.

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 polarizer.

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

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

manufacturing a display panel;

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

fixing the plurality of spacers to said surface onto which the spacers were dispersed;

after fixing the plurality of spacers, applying an adhesive layer onto the surface including the plurality of spacers; and

bonding the polarizer directly to the display panel with the adhesive layer and plurality of spacers therebetween, wherein the adhesive layer and the spacers are transparent.
