Abstract

An exemplary method for fabricating a liquid crystal panel includes: providing a first substrate ( 210 ); forming a plurality of color resin layers ( 212 ) and a black matrix ( 27 ) spacing the color resin layers on the first substrate; forming a plurality of compressible photo spacers ( 24 ) on the black matrix, the photo spacers comprising a plurality of photo spacers having a first length and a plurality of photo spacers having a second length different from the first length, wherein the first length and the second length are measured perpendicular to the first substrate; providing a second substrate; coating a sealant along an outer periphery of the second substrate, whereby the second substrate and the sealant cooperatively defining a space; dropping liquid crystal on the second substrate in the space; placing the first substrate onto the second substrate and pressing the first substrate; and curing the sealant.

Claims (17)

1. A method for fabricating a liquid crystal panel, the method comprising:

providing a first substrate;

forming a black matrix on the first substrate, a plurality of space areas being defined at the black matrix;

forming a plurality of color resin layers on the space areas and on parts of the black matrix;

forming a plurality of compressible first photo spacers on the black matrix and a plurality of compressible second photo spacers on the color resin layers that are formed on the black matrix, wherein a combined dimension of each of the second photo spacers and the corresponding color resin layer is greater than a corresponding length of each of the first photo spacers, the combined dimension of each of the second photo spacers and the corresponding color resin layer and the corresponding length of each of the first photo spacers being measured perpendicular to the first substrate;

providing a second substrate;

coating sealant on a periphery of the second substrate, whereby the second substrate and the sealant cooperatively define a space;

dropping liquid crystal on the second substrate in the space;

placing the first substrate on the second substrate and pressing the first substrate, wherein a resulting reduction in the length of at least one of the second photo spacers is different from a resulting reduction in the length of at least one of the first photo spacers; and

curing the sealant.

2. The method as claimed in claim 1 , wherein a difference between the combined dimension of each of the second photo spacers and the corresponding color resin layer and the corresponding length of each of the first photo spacers is in the range from 0.2˜5 millimeters.

3. The method as claimed in claim 2 , wherein the difference between the combined dimension of each of the second photo spacers and the corresponding color resin layer and the corresponding length of each of the first photo spacers is equal to approximately 3 millimeters.

4. The method as claimed in claim 1 , wherein the first photo spacers and the second photo spacers have the same length.

5. The method as claimed in claim 1 , wherein the color resin layers comprise red resin layers, green resin layers, and blue resin layers.

6. The method as claimed in claim 1 , wherein each of the second photo spacers is disposed between two adjacent color resin layers in the space areas having a same color.

7. The method as claimed in claim 1 , wherein each of the second photo spacers is disposed between two color resin layers in the space areas having different colors.

8. The method as claimed in claim 1 , wherein curing the sealant comprises using ultraviolet light to irradiate the sealant.
