Abstract

An electro-optical device includes an electro-optical panel and a backlight unit. A cover includes a window portion opened in correspondence with a pixel region of the electro-optical panel and a first sidewall provided so as to face the side surfaces of the electro-optical panel and the backlight unit. A frame holds the electro-optical panel and the backlight unit and has a second sidewall provided so as to face the side surfaces of the electro-optical panel and the backlight unit. The first sidewall has an engagement portion engaged with the backlight unit and the second sidewall has a protrusion for guiding the engagement portion to an engagement place.

Claims (31)

1. An electro-optical device comprising:

an electro-optical panel;

a backlight unit disposed so as to face the electro-optical panel;

a cover including a window portion opened in correspondence with a pixel region of the electro-optical panel and a first sidewall provided so as to face the side surfaces of the electro-optical panel and the backlight unit, the first sidewall having an engagement hole engaged with the backlight unit;

a frame which holds the electro-optical panel and the backlight unit and has a second sidewall provided so as to face the side surfaces of the electro-optical panel and the backlight unit, the second sidewall having a protrusion for guiding the engagement hole to an engagement place; and

an engagement protrusion provided so as to protrude from the side surface of the backlight unit,

wherein:

the cover and the backlight are fixed by engaging the engagement hole with the engagement protrusion, and

the protrusion is disposed at a position overlapping with the engagement protrusion in a planer manner.

2. The electro-optical device according to claim 1 , wherein:

the protrusion has a first surface formed on the side of the electro-optical panel and a second surface formed on the opposite side of the electro-optical panel, and

the first surface is formed of an inclined surface inclined in a direction away from the electro-optical panel.

3. The electro-optical device according to claim 1 , wherein the protrusion is provided so as to protrude further than the engagement protrusion.

4. An electronic apparatus comprising the electro-optical device according to claim 1 .

5. An electro-optical device comprising:

an electro-optical panel;

a backlight unit disposed so as to face the electro-optical panel;

a cover including a window portion opened in correspondence with a pixel region of the electro-optical panel and a first sidewall provided so as to face the side surfaces of the electro-optical panel and the backlight unit, the first sidewall having an engagement portion engaged with the backlight unit; and

a frame which holds the electro-optical panel and the backlight unit and has a second sidewall provided so as to face the side surfaces of the electro-optical panel and the backlight unit, the second sidewall having a protrusion for guiding the engagement portion to an engagement place,

wherein:

the protrusion has a first surface formed on the side of the electro-optical panel and a second surface formed on the opposite side of the electro-optical panel, and

the first surface is formed of an inclined surface inclined in a direction away from the electro-optical panel.

6. An electro-optical device comprising:

an electro-optical panel;

a backlight unit disposed so as to face the electro-optical panel;

a cover including a window portion opened in correspondence with a pixel region of the electro-optical panel and a first sidewall provided so as to face the side surfaces of the electro-optical panel and the backlight unit, the first sidewall having an engagement hole engaged with the backlight unit;

a frame which holds the electro-optical panel and the backlight unit and has a second sidewall provided so as to face the side surfaces of the electro-optical panel and the backlight unit, the second sidewall having a protrusion for guiding the engagement hole to an engagement place; and

an engagement protrusion provided so as to protrude from the side surface of the backlight unit,

wherein:

the cover and the backlight are fixed by engaging the engagement hole with the engagement protrusion, and

the protrusion is provided so as to protrude further than the engagement protrusion.
