Color blocking film layer 12 is less than the width of third color blocking film layer 13, and mutation portion 101 is located at the second color blocking film layer 12 and third color blocking film layer
13 intersection.
Further, on color membrane substrates further include: black matrix" 300；Black matrix" 300 is arranged on underlay substrate, black
Colour moment battle array 300, which is enclosed, to be set to form subpixel area, and single layer color blocking is provided in subpixel area, and color blocking lamination 100 is arranged in sub- picture
On black matrix" 300 between plain region.
In liquid crystal display panel, the common electrode layer 200 on color blocking lamination 100 contacts setting with array substrate.Due to
The entire common electrode layer 200 of common electrode layer 200 and other positions on color blocking lamination 100 disconnects, therefore, common electrode layer
200 increase at a distance from tft array substrate, effectively prevent the risk of short circuit and signal delay.
Liquid crystal display panel provided in an embodiment of the present invention serves as the effect of cylindrical spacer by the way that color blocking lamination is arranged,
And make the first part for the common electrode layer being layered on underlay substrate and the second part being layered on color blocking lamination open circuit
Setting, when color membrane substrates and array substrate contact work, common electrode layer increases at a distance from tft array substrate, effectively keeps away
The risk of short circuit and signal delay is exempted from.Further, cylindrical spacer is made by way of color blocking lamination, so that column
Spacer material can be formed with chromatic filter layer in same processing procedure, so as to simplify the preparation process of color membrane substrates, reduce life
Produce cost.
