ABSTRACT:
A liquid crystal display (LCD) that minimizes moire phenomenon to prevent display performance degradation in the LCD is provided. The present invention also minimizes loss of the light supplied to a LCD panel and achieves high luminance with low power consumption. When a light transforming unit for uniformly forming light distribution of light supplied from a light source is overlapped with a reflective electrode of the reflective type LCD, the moire is generated. The more and light leakage generated in the light transforming unit are prevented by changing in a structure of the light transforming unit. Therefore, a display operation of the reflective type LCD operates normally even in a dark place.
