Abstract

A display device includes a display section in which a plurality of pixels are arrayed in a matrix, a plurality of scan lines which select pixels, a plurality of signal lines which supply image signals to the selected pixels, and color filters that are arranged so as to correspond to color displays of the pixels. In the device, the display section includes an effective pixel portion and a frame portion that surrounds the effective pixel portion, and the frame portion and a wiring circuit of the effective pixel portion are covered with light-shielding layers, the light-shielding layers being separated from each other at a certain separation location in the display section, and a plurality of color filters having different colors are arranged by being stacked at the separation location.

Claims (41)

1. A display device comprising:

a display section including pixels;

scan lines configured to provide selected pixels among the pixels in the display section;

signal lines configured to supply image signals to the selected pixels;

a pixel substrate including the scan lines and the signal lines;

a counter substrate opposed to the pixel substrate; and

color filters that are arranged so as to correspond to color displays of the pixels,

wherein

the display section includes an effective pixel portion and a frame portion that surrounds the effective pixel portion,

the frame portion and a wiring circuit of the effective pixel portion are covered with a light-shielding layer including a slit portion,

the color filters include one or more slit color filters that are located under the slit portion,

wherein

the one or more slit color filters and the light-shielding layer are disposed on a pixel substrate side of the counter substrate, and

none of the one or more slit color filters is in direct contact with the pixel substrate.

2. The display device according to claim 1 , wherein the slit portion is located in close proximity to the effective pixel portion, and located outside the effective pixel portion.

3. The display device according to claim 1 , wherein the shape of the slit portion is a hollow square.

4. The display device according to claim 1 , wherein

the pixel substrate and the counter substrate that includes the light-shielding layer and the one or more slit color filters are bonded to each other by a seal material.

5. The display device according to claim 1 , wherein the pixels include three colors of red, green, and blue.

6. The display device according to claim 5 , wherein the slit portion is located in close proximity to the effective pixel portion, and located outside the effective pixel portion.

7. The display device according to claim 1 , wherein the pixels include four colors of red, green, blue, and white.

8. A method of manufacturing a display device that includes a display section that includes pixels, scan lines to provide selected pixels, signal lines that supply image signals to the selected pixels, a pixel substrate including the scan lines and the signal lines, a counter substrate opposed to the pixel substrate, and color filters that are arranged so as to correspond to color displays of the pixels, the method comprising:

covering a frame portion and a wiring circuit of an effective pixel portion in the display section with a light-shielding layer having a slit portion; and

arranging one or more slit color filters that are the color filters under the slit portion,

wherein

the one or more slit color filters and the light-shielding layer are disposed on a pixel substrate side of the counter substrate, and

none of the one or more slit color filters is in direct contact with the pixel substrate.

9. An electronic device including a display device comprising:

a display section including pixels;

scan lines configured to provide selected pixels among the pixels in the display section;

signal lines configured to supply image signals to the selected pixels;

a pixel substrate including the scan lines and the signal lines;

a counter substrate opposed to the pixel substrate; and

color filters that are arranged so as to correspond to color displays of the pixels,

wherein

the display section includes a frame portion and an effective pixel portion,

the frame portion and a wiring circuit of the effective pixel portion are covered with a light-shielding layer having a slit portion,

the color filters include one or more slit color filters that are located under the slit portion in the frame portion,

wherein

the one or more slit color filters and the light-shielding layer are disposed on a pixel substrate side of the counter substrate, and

none of the one or more slit color filters is in direct contact with the pixel substrate.
