Abstract

The present invention provides a liquid crystal display panel, which comprises a color film substrate, an array substrate and a liquid crystal layer sandwiched between the color film substrate and the array substrate, said array substrate has a pixel electrode where a surface is disposed with a number of recesses and a number of terraces, said number of recesses and said number of terraces are disposed in evenly intersectional arrangement, said respective recess is located at a position between two interconnected pixels, said respective recess is disposed with a first spacer, said respective terrace is disposed with a second spacer, a height of said first spacer protruded from said terrace is larger than a height of said second spacer protruded from said terrace, said first spacers and said second spacers are extended into the liquid crystal layer, for support of between said color film substrate and said array substrate.

First claim

What is claimed is:

1. A liquid crystal display panel, which comprises a color film substrate, an array substrate, and a liquid crystal layer sandwiched between the color film substrate and the array substrate, wherein said array substrate surface has a pixel electrode having a surface that is disposed with a number of recesses and a number of terraces, said number of recesses and said number of terraces being disposed in evenly intersectional arrangement, said respective recess being located at a position between two interconnected pixels, wherein said respective recess is disposed with a first spacer, and said respective terrace is disposed with a second spacer, such that said first spacer that is disposed in said respective recess has a distal end protruding beyond said respective terrace and a height of the distal end of said first spacer relative to said respective terrace is larger than a height of a distal end of said second spacer protruded from said respective terrace, said first spacers and said second spacers extending into the liquid crystal layer for supporting between said color film substrate and said array substrate.

2. Said liquid crystal display panel as claimed in claim 1 , wherein said array substrate comprises TFT switches, a gate insulation layer, an insulation layer covering said gate insulation layer and said TFT switches, a color resist layer stacked on the first insulation layer, and a second insulation layer covering said color resist layer, said pixel electrode is stacked on the second insulation layer.

3. Said liquid crystal display panel as claimed in claim 2 , wherein said respective terrace is a planar portion of said pixel electrode, said respective recess is an intersectional portion of the pixel electrode which is located on color resists of said color resist layer, and the recesses are lower than said terraces.

4. Said liquid crystal display panel as claimed in claim 1 , wherein said liquid crystal display panel is a flexible panel.

5. A curved-surface display apparatus, which comprises a liquid crystal display panel and a backlight module, wherein said backlight module provides a light source for the liquid crystal display panel; and said liquid crystal display panel comprises a color film substrate, an array substrate and a liquid crystal layer sandwiched between the color film substrate and the array substrate, wherein said array substrate has a pixel electrode having a surface that is disposed with a number of recesses and a number of terraces, said number of recesses and said number of terraces being disposed in evenly intersectional arrangement, said respective recess being located at a position between two interconnected pixels, wherein said respective recess is disposed with a first spacer, and said respective terrace is disposed with a second spacer, such that said first spacer that is disposed in said respective recess has a distal end protruding beyond said respective terrace and a height of the distal end of said first spacer relative to said respective terrace is larger than a height of a distal end of said second spacer protruded from said respective terrace, and said first spacers and said second spacers extending into the liquid crystal layer for supporting between said color film substrate and said array substrate.

6. Said curved-surface display apparatus as claimed in claim 5 , wherein said array substrate comprises TFT switches, a gate insulation layer, an insulation layer covering said gate insulation layer and said TFT switches, and a color resist layer stacked on the first insulation layer and a second insulation layer covering said color resist layer, said pixel electrode is stacked on the second insulation layer.

7. Said curved-surface display apparatus as claimed in claim 6 , wherein said respective terrace is a planar portion of said pixel electrode, said respective recess is an intersectional portion of the pixel electrode which is located on the color resists, and the recesses are lower than said terraces.

8. Said curved-surface display apparatus as claimed in claim 5 , wherein said liquid crystal display panel is a flexible panel.
