Abstract

A liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel comprises a color filter substrate and a thin film transistor array substrate arranged in parallel and a liquid crystal layer between the substrates. In addition, several spacers are disposed on a black matrix of the color filter substrate. These spacers lean on the edge of at least one of the gate layer lines and source layer lines on the thin film transistor array substrate. The invention increases the bonding stability between the color filter substrate and the thin film transistor array substrate so that the reliability and display quality of the liquid crystal display panel is improved.

Claims (24)

1. A liquid crystal display panel, comprising:

a color filter substrate;

a thin film transistor array substrate, disposed parallel to the color filter substrate, wherein the thin film transistor array substrate has a plurality of gate layer lines and a plurality of source layer lines thereon;

a plurality of spacers, disposed on the color filter substrate, wherein the spacers at least lean on one of the side edges of the gate layer lines or the source layer lines, and the spacers are disposed at the overlapping area between the gate layer lines and the source layer lines with the spacers leaning against both the gate layer lines and the source layer lines, wherein adjacent spacers are joined together on the color filter substrate to form a latching structure such that a central recess section of the latching structure is able to latch onto the overlapping area between the gate layer lines and the source layer lines; and

a liquid crystal layer, disposed between the color filter substrate and the thin film transistor array substrate.

2. The liquid crystal display panel of claim 1 , wherein the gate layer lines comprise scan lines and the source layer lines comprise data lines.

3. The liquid crystal display panel of claim 2 , wherein the gate layer lines further comprise common lines.

4. The liquid crystal display panel of claim 1 , wherein the spacers have a cylindrical or a wall-like shape.

5. A liquid crystal display panel, comprising:

a color filter substrate;

a thin film transistor array substrate, disposed parallel to the color filter substrate, wherein the thin film transistor array substrate has a plurality of gate layer lines and a plurality of source layer lines thereon;

a plurality of spacers, disposed on the color filter substrate, wherein the spacers at least lean on one of the side edges of the gate layer lines or the source layer lines, and the spacers are disposed on opposite sides of the gate layer lines with the spacers leaning against the gate layer lines as well, wherein adjacent spacers are joined together on the color filter substrate to form a latching structure such that a central recess section of the latching structure is able to latch onto the gate layer lines; and

a liquid crystal layer, disposed between the color filter substrate and the thin film transistor array substrate.

6. The liquid crystal display panel of claim 5 , wherein the gate layer lines comprise scan lines and the source layer lines comprise data lines.

7. The liquid crystal display panel of claim 6 , wherein the gate layer lines further comprise common lines.

8. The liquid crystal display panel of claim 5 , wherein the spacers have a cylindrical or a wall-like shape.
