Liquid crystal display panel
View Patent ↗The present invention discloses a liquid crystal display panel, including an array substrate; a color filter substrate; and primary post spacers and secondary post spacers disposed between the array substrate and the color filter substrate, wherein the color filter substrate is divided into a side portion and a central portion inside the side portion, and the density of the secondary post spacers in the central portion is less than that in the side portion.
1. A liquid crystal display (LCD) panel, comprising:
an array substrate;
a color filter substrate including a pixel area; and
primary post spacers and secondary post spacers disposed between the array substrate and the color filter substrate,
wherein the primary post spacers are higher than the secondary post spacers and contact the array substrate, and the secondary post spacers do not contact the array substrate or any component of the array substrate, and
wherein the color filter substrate is divided into a side portion at least partially within the pixel area and a central portion inside the side portion, the side portion and the central portion are arranged side by side, the division being at a location line where the density of the secondary post spacers changes from one side of the location line to the other, and the density of the secondary post spacers in the central portion is less than that in the side portion.
2. The LCD panel of claim 1 , wherein the density of the secondary post spacers in the central portion is about ½ of that in the side portion.
3. The LCD panel of claim 2 , wherein the density of the secondary post spacers in the central portion is about ⅔ of that in the side portion.
4. The LCD panel of claim 1 , wherein the central portion is further divided into a first central portion and a second central portion inside the first central portion, and the density of the secondary post spacers in the second central portion is less than that in the first central portion.
5. The LCD panel of claim 4 , wherein the density of the secondary post spacers in the second central portion is about ¼-⅗ of that in the first central portion.
6. The LCD panel of claim 5 , wherein the density of the secondary post spacers in the second central portion is about ½ of that in the first central portion.
7. The LCD panel of claim 4 , wherein the length of a first pair of opposite sides of the second central portion in a lengthwise direction is about ½ of that of the corresponding sides of the first central portion, and the length of a second pair of opposite sides of the second central portion in a widthwise direction is about ⅓-⅔ of that of the corresponding sides of the first central portion.
8. The LCD panel of claim 7 , wherein the length of the first pair of opposite sides of the second central portion is about ⅔ of that of the corresponding sides of the first central portion, and the length of the second pair of opposite sides of the second central portion is about ½ of that of the corresponding sides of the first central portion.
9. The LCD panel of claim 1 , wherein the length of a first pair of opposite sides of the central portion in a lengthwise direction is about ½ of that of the corresponding sides of the color filter substrate, and the length of a second pair of opposite sides in a widthwise direction is about ⅓-⅔ of that of the corresponding sides of the color filter substrate.
10. The LCD panel of claim 9 , wherein the length of the first pair of opposite sides of the central portion is about ⅔ of that of the corresponding sides of the color filter substrate, and the length of the second pair of opposite sides of the central portion is about ½ of that of the corresponding sides of the color filter substrate.
11. A liquid crystal display (LCD) panel, comprising:
an array substrate;
a color filter substrate; and
primary post spacers and secondary post spacers disposed between the array substrate and the color filter substrate,
wherein the secondary post spacers do not contact the array substrate or any component of the array substrate,
wherein the primary post spacers are higher than the secondary post spacers and contact the array substrate, and the color filter substrate is divided into a side portion and a central portion inside the side portion, the side portion and the central portion are arranged side by side, the division being at a location line where the density of the secondary post spacers changes from one side of the location line to the other, and the density of the secondary post spacers in the central portion is less than that in the side portion, wherein the length of a first pair of opposite sides of the central portion in a lengthwise direction is about ½ of that of the corresponding sides of the color filter substrate, and the length of a second pair of opposite sides in a widthwise direction is about ⅓-⅔ of that of the corresponding sides of the color filter substrate.
12. The LCD panel of claim 11 , wherein the length of the first pair of opposite sides of the central portion is about ⅔ of that of the corresponding sides of the color filter substrate, and the length of the second pair of opposite sides of the central portion is about ½ of that of the corresponding sides of the color filter substrate.
13. A liquid crystal display (LCD) panel, comprising:
an array substrate;
a color filter substrate including a pixel area; and
primary post spacers and secondary post spacers disposed between the array substrate and the color filter substrate,
wherein the primary post spacers are higher than the secondary post spacers and contact the array substrate, and the secondary post spacers do not contact the array substrate or any component of the array substrate, and
wherein the color filter substrate is divided into a first portion and a second portion at least within the pixel area, the first portion and the second portion are arranged side by side, light leakage is more prone to occur in the first portion than the second portion, and the density of the secondary post spacers in the first portion is less than that in the second portion; and
the division being at a location line where the density of the secondary post spacers changes from one side of the location line to the other.
14. The LCD panel of claim 13 , wherein the density of the secondary post spacers in the first portion is about ½ of that in the second portion.
15. The LCD panel of claim 13 , wherein the density of the secondary post spacers in the first portion is about ⅔ of that in the second portion.
16. The LCD panel of claim 13 , wherein the first portion is surrounded by the second portion.
