Abstract

The invention provides an optical element of a liquid crystal display and manufacturing method thereof, wherein the optical element of the liquid crystal display is an optical element positioned between a white light backlight source and a color film substrate and is distributed red particles. The invention further provides a liquid crystal display, comprising the white light backlight source andthe color film substrate, wherein the optical element of the liquid crystal display is arranged between the white light backlight source and the color film substrate. The invention further provides amethod for manufacturing a light guide plate and an optical film of the liquid crystal display. The optical element of the liquid crystal display and manufacturing method provided by the invention can change intensity ratio of the red light, the green light and the blue light penetrating through the optical element in backlight, increase the proportion of the red light by adding the red particlesin the optical element so as to solve the partial color problem of the white light as the backlight source which is obtained by means of exciting the yellow fluorescent powders by the blue light, andimprove the picture quality of the liquid crystal display using the white light backlight source.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an optical element of a liquid crystal display and a manufacturing method thereof. Background technique [0002] With the increasing maturity of thin film transistor liquid crystal display technology and the need for energy saving, Light Emitting Diode (hereinafter referred to as: LED) has gradually replaced cold cathode fluorescent lamp (hereinafter referred to as: CCFL) as the mainstream backlight A liquid crystal display (Liquid Crystal Display, hereinafter referred to as LCD) using LEDs as a backlight has the advantages of energy saving, environmental protection, and long life. There are two types of LED backlight, one of which is RGB LED backlight with three primary colors, the price of this type of backlight is higher, and the other uses white LED as LCD backlight. [0003] The light emitted by the backlight needs to pass through optical elements such as the...
