Image display device
View Patent ↗An image display device, includes a light and an array substrate having a plurality of sub-pixel areas and corresponding to a plurality of color filters. A liquid crystal layer includes a plurality of liquid crystal molecules, wherein the liquid crystal molecules corresponding to different color filters have different derangements, and a light transmittance per unit area in the peripheral region of the array substrate is equal to or less than a light transmittance per unit area in the display region of the array substrate.
1. An image display device, comprising:
a light source;
an array substrate comprising a plurality of sub-pixel areas and corresponding to a plurality of color filters, and the array substrate comprising:
a display region having a first light-shielding portion and a first non-light-shielding portion, and
a peripheral region around the display region, and the peripheral region having a second light-shielding portion and a second non-light-shielding portion; and
a liquid crystal layer comprising a plurality of liquid crystal molecules;
wherein the liquid crystal molecules corresponding to different color filters have different electric field magnitudes when a voltage is applied to generate an electric field, and a light transmittance per unit area acquired after light from the light source passes the second light-shielding portion and the second non-light-shielding portion in the peripheral region of the array substrate is equal to or less than a light transmittance per unit area acquired after light from the light source passes the first light-shielding portion and the first non-light-shielding portion in the display region of the array substrate,
wherein an absolute value of a light transmittance difference between the peripheral region and the display region, which are acquired after light from the light source respectively passes the second light-shielding portion and the second non-light-shielding portion and passes the first light-shielding portion and the first non-light-shielding portion, is less than or equal to 950 cd/m 2 .
2. The image display device of claim 1 , wherein the product of light transmittance acquired after light from the light source passes the first light-shielding portion and the first non-light-shielding portion of the display region and pixel numbers per inch is less than 10 6 cd/m 2 *PPI and greater than 0 cd/m 2 *PPI.
3. The image display device of claim 1 , wherein the array substrate further comprises:
a first light-shielding wiring layout arranged in the display region of the array substrate as the first light-shielding portion; and
a second light-shielding wiring layout arranged in the peripheral region of the array substrate as the second light-shielding portion, an occupied area per unit area of the second light-shielding wiring layout in the peripheral region being equal to or greater than an occupied area per unit area of the first light-shielding wiring layout in the display region.
4. The image display device of claim 3 , wherein the second light shielding wiring layout includes a plurality of electrical lines, and a line width of one of the electrical lines is larger than that of the other electrical lines, and the occupied area per unit area of the second light shielding wiring layout to be equal to or greater than the occupied area per unit area of the first light shielding wiring layout.
5. The image display device of claim 3 , wherein the second light shielding wiring layout includes at least one electrical line having a line width, and the line width is enlarged, and the occupied area per unit area of the second light shielding wiring layout to be equal to or greater than the occupied area per unit area of the first light shielding wiring layout.
6. The image display device of claim 3 , wherein the second light-shielding wiring layout includes a dummy pattern.
7. The image display device of claim 6 , wherein a width of the dummy pattern is larger than one of the other line widths of the second light-shielding wiring layout.
