Abstract

An electro-optical device includes an electro-optical panel, a lighting unit that is disposed to overlap with the electro-optical panel in a plan view and that irradiates the electro-optical panel, and a frame-shaped holding member that has an adhesive layer for holding the electro-optical panel and the lighting unit. The holding member is provided at an outer peripheral end surface of the electro-optical panel and an outer peripheral end surface of the lighting unit, and fixes the electro-optical panel and the lighting unit.

Claims (13)

1. An electro-optical device comprising:

an electro-optical panel;

a lighting unit that is disposed to overlap with the electro-optical panel in a plan view and that irradiates the electro-optical panel; and

a frame-shaped holding member that has an adhesive layer for holding the electro-optical panel and the lighting unit,

wherein the holding member is provided at an outer peripheral end surface of the electro-optical panel and an outer peripheral end surface of the lighting unit, and fixes the electro-optical panel and the lighting unit.

2. The electro-optical device according to claim 1 , wherein the adhesive layer is disposed from the outer peripheral end surface of the electro-optical panel to the outer peripheral end surface of the lighting unit.

3. The electro-optical device according to claim 2 , wherein the adhesive layer is formed of a tape.

4. The electro-optical device according to claim 2 , wherein the holding member includes the adhesive layer and a holding frame constituting a part of a frame.

5. The electro-optical device according to claim 4 , wherein the adhesive layer is formed of a tape, and the tape is disposed from an end surface of the holding frame to the outer peripheral end surface of the electro-optical panel and the outer peripheral end surface of the lighting unit.

6. The electro-optical device according to claim 2 , wherein the lighting unit includes a light guide plate and an optical sheet disposed between the light guide plate and the electro-optical panel, the adhesive layer is disposed from the outer peripheral end surface of the electro-optical panel to an outer peripheral end surface of the optical sheet.

7. An electronic apparatus comprising:

the electro-optical device according to claim 1 ; and

a control unit for controlling the electro-optical device.
