Abstract

Embodiments of the present invention provide a substrate of a liquid crystal display (LCD) panel, a liquid crystal panel, and a manufacturing method thereof. The substrate of a LCD panel comprises a first substrate, a color filter layer comprising color resins and a black matrix and formed on one surface of the first substrate, a transparent layer formed on the color filter layer and having a planar surface, and an array structure layer formed on the planar surface of the transparent layer or on the other surface of the first substrate.

Claims (41)

1. A substrate adapted to be disposed opposite to a common substrate with an interposed liquid crystal layer to form a liquid crystal display (LCD) panel, comprising:

a first substrate;

a color fitter layer comprising color resins and a black matrix and formed on one surface of the first substrate;

a transparent layer formed on the color filter layer and having a planar surface; and

an array structure layer formed on the other surface of the first substrate.

2. The substrate claim 1 , wherein the color filter layer comprises:

a red color resin, a green color resin, and a blue color resin, which are formed on the surface of the first substrate; and

the black matrix formed among the red color resin, the green color resin, and the blue color resin.

3. The substrate claim 1 , wherein the color filter layer comprises:

the black matrix formed on the surface of the first substrate; and

a red color resin, a green color resin, and a blue color resin formed in the black matrix.

4. The substrate claim 1 , wherein the material of the transparent layer is a transparent material with characteristics of solidifying stability.

5. The substrate claim 1 , wherein an alignment mark as an alignment reference for forming the array structure layer is formed on the first substrate, so that the color filter layer and the array structure layer are accurately aligned with an alignment deflection of less than about 1.5 μm.

6. The substrate claim 1 , further comprising a common electrode structure in the array structure layer.

7. A liquid crystal display (LCD) panel, comprising a color/array substrate, a common substrate assembled with the color filter/array substrate, and a liquid crystal layer filled between the color filter/array substrate and the common substrate, wherein

the color filter/array substrate comprises:

a first substrate;

a color filter layer comprising color resins and a black matrix and formed on one surface of the first substrate;

a transparent layer formed on the color filter layer and having a planar surface; and

an array structure layer formed on the other surface of the first substrate.

8. The LCD panel of claim 7 , wherein the color filter/array substrate further comprises a common electrode structure in the array structure layer.

9. The LCD panel of claim 7 , wherein the common substrate comprises a second substrate and a common electrode layer on a surface of the second substrate facing the color filter/array substrate.

10. A method of manufacturing a substrate adapted to be disposed opposite to a common substrate with an interposed liquid crystal layer to form a liquid crystal display (LCD) panel, comprising:

forming a color filter layer on one surface of a first substrate;

forming a transparent layer with a planar surface on the color filter layer; and

forming an array structure layer on the other surface of the first substrate.

11. The method of claim 10 , wherein forming the color filter layer on the surface of the first substrate comprises:

forming a red color resin, a green color resin, and a blue color resin on the surface of the first substrate, respectively; and

forming a black matrix among the red color resin, the green color resin, and the blue color resin.

12. The method of claim 10 , wherein forming the color filter layer on the surface of the first substrate further comprises:

forming an alignment mark on the first substrate as an alignment reference for forming the array structure layer.

13. A method of manufacturing a liquid crystal display (LCD) panel, comprising:

preparing a color filter/array substrate and a common substrate, respectively; and

assembling the color filter/array substrate and the common substrate together with an liquid crystal layer interposed between the substrates, wherein preparing the color filter/array substrate comprises:

forming a color filter layer on one surface of a first substrate;

forming a transparent layer with a planar surface on the color filter layer; and

forming an array structure layer on the other surface of the first substrate.

14. The method of claim 13 , wherein assembling the color filter/array substrate and the common substrate comprises:

the color filter/array substrate and the common substrate are used as an upper substrate and a lower substrate, and the assembling is completed by processes comprising alignment film applying, rubbing, liquid crystal filling, bonding, and cutting.

15. The method of claim 14 , wherein assembling the color filter/array substrate and the common substrate further comprises:

forming column spacers on the color filter/array substrate or the common substrate.
