Abstract

A reflective plate used in a liquid crystal display including a substrate, a first peak and depression layer of organic insulator on the substrate, a second peak and depression layer of organic insulator overlapping with the first peak and depression layer, and a reflective layer on the first and second peak and depression layers.

Claims (12)

1. A reflective plate used in a liquid crystal display comprising:

a substrate;

a plurality of first peak patterns of organic insulator on the substrate;

a plurality of second peak patterns of organic insulator, each of the second peak patterns being formed between the first peak patterns; and

a reflective layer on the first and second peak patterns.

2. The reflective plate according to claim 1 , wherein the organic insulator is a photosensitive resin film.

3. The reflective plate according to claim 1 , wherein each of the first peak patterns has a plurality of first peaks and each of the second peak patterns has a plurality of second peaks, wherein a highest point of each of the first peaks is located at different locations from a highest point of each of the second peaks.

4. The reflective plate according to claim 1 , wherein each of the first peak patterns comprises a plurality of first peaks and each of the second peak patterns comprises a plurality of second peaks, wherein a center of each of the first peaks is located at different location from a center of each of the second peaks.

5. The reflective plate according to claim 1 , wherein each of the first peak patterns comprises a plurality of first peaks and each of the second peak patterns comprises a plurality of second peaks overlapped with the first peaks.

6. The reflective plate according to claim 1 , wherein the first and second peak patterns have a plurality of peaks that are randomly arranged.

7. The reflective plate according to claim 1 , wherein each of the first peak patterns comprises a plurality of first peaks and each of the second peak patterns comprises a plurality of second peaks overlapped with portions of the first peaks with a height less than one half height of the first peaks.

8. The reflective plate according to claim 1 , wherein a reflecting surface formed by the first and second peak patterns has final peak shapes in which a ratio of a height to a radius of the peak is 1:10.
