Abstract

A liquid crystal display (LCD) device and a method of manufacturing the same that can improve the picture quality are provided. A liquid crystal display device includes: a first substrate; a black matrix formed in a matrix configuration on the first substrate; a compensation layer disposed above the black matrix and including a plurality of compensation patterns separated a predetermined region from each other where the compensation layer has been removed; and a column spacer disposed in a region including at least the predetermined region.

Claims (35)

1. A liquid crystal display device comprising:

a first substrate;

a black matrix formed in a matrix configuration on the first substrate;

a compensation layer capable of compensating the optical phase difference disposed above the black matrix and including a plurality of compensation patterns separated by a predetermined region from each other where the compensation layer has been removed;

a color filter layer disposed between patterns of the black matrix; and

a column spacer disposed in a region including at least the predetermined region,

wherein the color filter layer has a stripe configuration,

wherein the color filter layer comprises color filters spaced apart by a predetermined interval from one another in a first direction on the black matrix,

wherein the color filter layer covers an overall portion of an upper surface of the black matrix in a second direction,

wherein the column spacer is formed on the predetermined region and a partial region of the compensation patterns,

wherein a common electrode is formed on the black matrix and the compensation patterns of the first substrate, and

wherein the column spacer is contacted with the common electrode corresponding to the predetermined region of the compensation patterns.

2. The liquid crystal display device according to claim 1 , further comprising: a pixel electrode formed on a second substrate, wherein a seal pattern is formed on the common electrode.

3. The liquid crystal display device according to claim 1 , wherein the common electrode includes a groove recessed toward the black matrix, and the column spacer is formed on the groove of the common electrode.

4. The liquid crystal display device according to claim 1 , wherein the compensation patterns are not formed on the first substrate corresponding to the edge region.

5. The liquid crystal display device according to claim 1 , wherein the compensation patterns are formed of a reactive mesogen.

6. A liquid crystal display device comprising:

a first substrate;

a black matrix formed in a matrix configuration on the first substrate;

a compensation layer capable of compensating the optical phase difference disposed above the black matrix and including a plurality of compensation patterns separated by a predetermined region from each other where the compensation layer has been removed;

a column spacer disposed in a region including at least the predetermined region;

a second substrate disposed facing the first substrate;

a liquid crystal layer interposed between the first substrate and the second substrate, and

a color filter layer disposed between patterns of the black matrix,

wherein the second substrate includes a pixel electrode,

wherein the color filter layer has a stripe configuration,

wherein the color filter layer comprises color filters spaced apart by a predetermined interval from one another in a first direction on the black matrix,

wherein the color filter layer covers an overall portion of an upper surface of the black matrix in a second direction,

wherein the column spacer is formed on the predetermined region and a partial region of the compensation patterns,

wherein a common electrode is formed on the black matrix and the compensation patterns of the first substrate, and

wherein the column spacer is contacted with the common electrode corresponding to the predetermined region of the compensation patterns.

7. The liquid crystal display device according to claim 6 , further comprising a seal pattern formed in an edge region of the first and second substrates.

8. The liquid crystal display device according to claim 7 , wherein the compensation patterns are not formed on the first substrate corresponding to the edge region.

9. The liquid crystal display device according to claim 7 , wherein the seal pattern is directly formed on the first substrate.

10. The liquid crystal display device according to claim 6 , wherein the compensation patterns are formed of a reactive mesogen.
