Problems solved by technology

[0004] Since the white light emitted by the white LED backlight is mixed with light of various wavelengths, when the white light passes through the liquid crystal layer, the optical anisotropy of different wavelengths is different, and the light of each wavelength will form different phase retardation , and thus lead to color shift, which affects the display effect of the LCD panel

Abstract

The invention provides a LCD (liquid crystal display) panel and a manufacturing method thereof, relates to the field of manufacturing of liquid crystal displays, and the LCD panel can avoid color cast of a display panel caused by different phase differences formed when visible lights with different wavelengths transmitted by a conventional white backlight pass through a liquid crystal layer. The LCD panel comprises an LED (light-emitting diode) backlight, a color film substrate molded by paired boxes, a TFT (thin film transistor) array substrate, and a liquid crystal layer positioned between the color film substrate and the TFT array substrate, wherein the color film substrate comprises an orientation film, a common electrode layer and a color filter, the LED backlight comprises a plurality of primary LED chips, and phosphor layers in complementary color with the primary LED chips are arranged on the color film substrate and between the orientation film and the color filter. The method provided by the invention is used for manufacturing the LCD panel.

Description

technical field [0001] The invention relates to the field of liquid crystal display manufacturing, in particular to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Field Effect Transistor Liquid Crystal Display) uses the change of the electric field intensity set on the liquid crystal layer to change the degree of rotation of liquid crystal molecules, thereby controlling the intensity of light transmission to display images . Generally speaking, a complete liquid crystal display panel must be composed of a backlight module, a polarizer, a color filter substrate, a TFT array substrate, and a liquid crystal molecule layer filled in a box composed of these two substrates. [0003] Now, in the backlight module, the white LED backlight is gradually replacing the traditional fluorescent lamp backlight due to its low power consumption and other advantages. At present, ...
