Abstract

A display device which is an electro-optical device includes a panel including a first substrate, a second substrate, and a liquid crystal layer and having a display region, a transparent region provided inside the display region, and a frame region provided between the transparent region and the display region. A backlight unit is provided below the panel so as not to overlap with the transparent region. A bezel is provided below the backlight unit so as not to overlap with the transparent region. A cover member is provided above the second substrate so as to overlap with the transparent region. Also, a cap film made of a material different from that of the bezel covers at least a lateral side of the backlight unit in the frame region.

Claims (44)

1. An electro-optical device comprising:

a camera module;

a panel including a first substrate, a second substrate provided above the first substrate, and an electro-optical layer formed between the first substrate and the second substrate;

a polarizing plate on the first substrate along a thickness direction of the panel;

an opening formed in the polarizing plate;

a backlight unit provided below the polarizing plate along the thickness direction so as not to overlap with the opening of the polarizing plate in a plan view;

a bezel provided below the backlight unit along the thickness direction, and partially overlapping with the opening of the polarizing plate along the thickness direction, in the plan view; and

a light blocking material,

wherein the electro-optical layer overlaps the opening of the polarizing plate,

a part of the first substrate is exposed from the polarizing plate in the opening of the polarizing plate, where the opening of the polarizing plate is located,

the opening of the polarizing plate overlaps the camera module,

the bezel includes a bottom portion configured to cover a lower side of the backlight unit, a side portion provided on a lateral side of the backlight unit around the opening of the polarizing plate, and an upper portion partially overlapping with the opening of the polarizing plate,

the polarizing plate and the upper portion are adhered to each other by an adhesive layer,

the polarizing plate includes a side portion that defines the opening of the polarizing plate,

the light blocking material covers the side portion of the polarizing plate, and

the light blocking material contacts the first substrate inside of the opening of the polarizing plate.

2. The electro-optical device of claim 1 ,

wherein the side portion of the polarizing plate is located closer to a center of the opening than the side portion of the bezel.

3. The electro-optical device of claim 2 ,

wherein the polarizing plate overlaps the side portion and the upper portion of the bezel.

4. The electro-optical device of claim 3 ,

wherein the light blocking material includes a first portion and a second portion,

the first portion of the light blocking material faces the side portion of the polarizing plate and extends parallel to the side portion of the bezel,

the second portion of the light blocking material overlaps the polarizing plate and extends parallel to the bottom portion of the bezel, and

each of the first portion and the second portion contacts the upper portion of the bezel.

5. The electro-optical device of claim 4 ,

wherein the first portion of the light blocking material contacts the first substrate inside of the opening of the polarizing plate, and

the second portion of the light blocking material contacts the side portion of the bezel.

6. The electro-optical device of claim 5 ,

wherein the light blocking material is an adhesive layer.

7. The electro-optical device of claim 1 ,

wherein the side portion of the polarizing plate is located outer from a center of the opening than the side portion of the bezel.

8. The electro-optical device of claim 7 ,

wherein the side portion of the polarizing plate overlaps the bottom portion of the bezel and does not overlap the side portion and the upper portion of the bezel.

9. The electro-optical device of claim 8 ,

wherein the light blocking material includes a first portion and a second portion,

the first portion of the light blocking material faces the side portion of the polarizing plate and extends parallel to the side portion of the bezel,

the second portion of the light blocking material extends parallel to the bottom portion of the bezel, and

each of the first portion and the second portion contacts with the upper portion of the bezel.

10. The electro-optical device of claim 9 ,

wherein the first portion of the light blocking material contacts the first substrate inside of the opening of the polarizing plate, and

the second portion of the light blocking material contacts the side portion of the bezel.

11. The electro-optical device of claim 10 ,

wherein the light blocking material is an adhesive layer.
