Disclosed are an optical element which offers certain direction of light diffusion by disposing, in a resin having a refractive index n1, an anisotropic polymer having a refractive index n2 different from n1 in a predetermined direction, and a display device including the same. Such control of viewing angles is possible without using any louver pattern and eliminates the necessity of an additional brightness enhancement film, thus advantageously decreasing manufacturing costs and preventing defects such as diagonal line spots.

Optical element and display device having the same

An apparatus and method for driving a liquid crystal display (LCD) device is disclosed. The apparatus for driving a liquid crystal display (LCD) device includes a liquid crystal display (LCD) panel for receiving a video signal and a clock signal, and displaying them, a backlight for emitting light on the LCD panel, a timing controller for controlling the LCD panel and the backlight, a signal generator which has the same frequency as that of a horizontal synchronous signal by modulating the clock signal, and generates a signal synchronized with the horizontal synchronous signal, and an inverter which receives a signal from the signal generator, allows a driving frequency of the light source to be the same as that of the horizontal synchronous signal, and allows the received signal to be synchronized with the horizontal synchronous signal.
