Display panel
View Patent ↗A display panel comprises a first substrate, a second substrate and a black matrix disposed between the first substrate and the second substrate. The first substrate includes a plurality of pixel areas arranged in a matrix, and each of the pixel areas has a plurality of sub-pixel areas. The second substrate is disposed on the first substrate. The black matrix comprises a plurality of row shading bars and a plurality of column shading bars. The row shading bars are disposed between the two adjacent pixel areas and extend along a first direction, and have a first thickness. The column shading bars are disposed between the two adjacent sub-pixel areas and extend along a second direction, and have a second thickness. The second thickness is different from the first thickness and the first direction is different from the second direction.
1. A display panel, comprising:
a first substrate including a plurality of scan lines and a plurality of data lines, wherein the plurality of scan lines and the plurality of data lines are substantially perpendicular to each other to define a pixel matrix, the pixel matrix includes a plurality of pixel areas, and the plurality of scan lines extend along a first direction;
a second substrate disposed opposite to the first substrate, wherein the second substrate has a first surface closer to the first substrate; and
a black matrix disposed between the first substrate and the second substrate, and comprising:
a plurality of first parts, wherein one of the plurality of first parts extends along the first direction and is disposed between two adjacent pixel areas of the plurality of pixel areas, and the one of the plurality of first parts has a second surface closer to the first surface; and
a second part connected to the one of the plurality of first parts and extending along a second direction, wherein the second direction is different from the first direction, the second part has a third surface closer to the first surface, an end edge of an end of the second part is not parallel to a first edge of the one of the plurality of first parts, and there are at least three different distances between the end edge and the first edge,
wherein a vertical distance from the second surface to the first surface is defined as a first distance, a vertical distance from the third surface to the first surface defines as a second distance, and the second distance is different from the first distance.
2. The display panel as recited in claim 1 , wherein the first distance is less than the second distance.
3. The display panel as recited in claim 1 , the end of the second part is connected to another one of the plurality of first parts adjacent to the one of the plurality of first parts.
4. The display panel as recited in claim 1 , wherein a thickness of the one of the plurality of first part is between 1.2 μm and 2.0 μm.
5. The display panel as recited in claim 1 , wherein a thickness of the second part is between 0.5 μm and 1.0 μm.
6. The display panel as recited in claim 1 , further comprising:
a plurality of color filter blocks, wherein each of the color filter blocks is disposed between two adjacent first parts of the plurality of first parts.
7. The display panel as recited in claim 6 , wherein the plurality of color filter blocks are disposed between the black matrix and the first substrate.
8. The display panel as recited in claim 1 , wherein the first direction and the second direction are perpendicular to the normal direction of the first substrate.
9. The display panel as recited in claim 1 , wherein the first substrate or the second substrate comprises glass, quartz, or organic polymer.
10. The display panel as recited in claim 1 , wherein a display medium is disposed between the first substrate and the second substrate, and the display medium contains liquid crystal material, plasma material or organic electroluminescent material.
11. The display panel as recited in claim 1 , wherein the display panel is a liquid crystal display panel, a plasma display panel or an organic light emitting display panel.
12. The display panel as recited in claim 1 , wherein the plurality of the first parts correspond to the plurality of the scan lines respectively.
