Problems solved by technology

[0009] However, the existing compensation film can only perform phase compensation based on light of a specific wavelength (such as green light), and the compensation effect for light of other wavelengths (such as red or blue) is not ideal.
Therefore, the color shift compensation effect of the compensation film for light of different wavelengths is inconsistent, which in turn causes color distortion in subsequent imaging.

Embodiment Construction

[0022] The foregoing implementation manners will be described in detail below in conjunction with specific embodiments of liquid crystal displays.

[0023] In the prior art, the color shift compensation effect of the compensation film for light of different wavelengths is not consistent, and the inventor has conducted detailed research on this.

[0024] The phase difference δ can be expressed as δ=2π*Δn*d / λ, where Δn is the birefringence coefficient of liquid crystal molecules; d is the cell spacing, that is, the distance between the array substrate 12 and the opposite substrate 11; λ is the wavelength of light.

[0025] In existing liquid crystal display devices, the birefringence coefficient Δn of the liquid crystal molecules in all pixel regions is the same; the distance between the array substrate and the opposite substrate in all pixel regions is also the same, that is, the cell spacing d is also the same; but the corresponding The wavelength λ of light in different pixel...

Abstract

The invention relates to a liquid crystal display device which comprises an array substrate, an opposed substrate and liquid crystal molecules located between the array substrate and the opposed substrate, and at least one side of the array substrate and the opposed substrate is provided with a compensation film; the liquid crystal display device further comprises a red pixel, a green pixel and a blue pixel, wherein the liquid crystal molecules in the red pixel region, the green pixel region and the blue pixel region have different double refraction coefficients. The invention facilitates hue errors in the three pixel regions to be kept consistent by setting the liquid crystal molecules in the red pixel region, the green pixel region and the blue pixel region with different double refraction coefficients, so that the current ordinary compensation films can effectively compensate the three pixel regions simultaneously.

Description

technical field [0001] The invention relates to the technical field of TFT-LCD (thin film transistor liquid crystal display) manufacturing, in particular to a liquid crystal display device. Background technique [0002] In recent years, the rapid development of the information and communication field has increased the demand for various types of display devices. The current mainstream display devices mainly include: Cathode Ray Tube Display (CRT), Liquid Crystal Display (LCD), Plasma Display (PDP), Electroluminescent Display (ELD) and Vacuum Fluorescent Display (VFD). [0003] With the rapid progress of thin film transistor manufacturing technology, liquid crystal display has become the mainstream trend of display device development due to its advantages of thinness, lightness, power saving, and no radiation. It is widely used in various electronic products such as personal digital assistants (PDAs), notebook computers, digital cameras, camcorders, and mobile phones. [00...
