Reflective plate of LCD and fabrication method thereof
View Patent ↗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.
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.
