Embodiment Construction

[0031] In the following, each embodiment is described in detail and examples accompanied by drawings are used as a reference basis of the present invention. In the drawings or descriptions in the specification, the same figure numbers are used for similar or identical parts. And in the drawings, the shape or thickness of the embodiments may be enlarged, and marked for simplicity or convenience. Furthermore, parts of the components in the drawings will be described separately. It should be noted that the components not shown or described in the drawings are forms known to those skilled in the art.

[0032] The purpose of the present invention is to provide a liquid crystal display device, which can increase the transmittance of the entire display area without gray scale inversion phenomenon. The liquid crystal display device uses a liquid crystal material mixed with a chiral agent (Chiral) as the liquid crystal. The liquid crystal layer of a display device.

Abstract

The invention provides a liquid crystal display device which comprises a first substrate, a second substrate, a first polaroid, a second polaroid and a liquid crystal layer mixed with chiral materials. The first substrate is provided with a pixel unit which is provided with a pixel electrode. The second substrate is provided with an opposite electrode. The first polaroid is arranged below the first substrate. The second polaroid is arranged above the second substrate, and the polarized light axis of second polaroid is perpendicular to the polarized light axis of the first polaroid. The liquid crystal layer mixed with the chiral materials is arranged between the first polaroid and the second polaroid, wherein liquid crystal molecule torsional capacity (d / p) of the liquid crystal layer mixed with the chiral materials is 0.2<d / p<0.3, and optic phase retardation (R) is 0.6<R<0.95, wherein the d is the thickness of the liquid crystal layer, the p is the pitch of the chiral material, delta n is double refraction coefficient of the liquid crystal layer mixed with the chiral materials, and lambada is the optical wavelength of incident light.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display, which has high transmittance characteristics and can avoid gray scale inversion phenomenon. Background technique [0002] The liquid crystal display device utilizes the property that liquid crystal molecules have different polarization or refraction effects on light in different alignment states to control the amount of light transmitted, thereby enabling the liquid crystal display device to generate images. Traditional Twisted Nematic (TN) liquid crystal display devices have very good transmission properties, but are affected by the liquid crystal molecular structure and optical properties, and relatively narrow viewing angles. Therefore, how to make the display have both a wide viewing angle and a high light utilization rate will create a new breakthrough in panel display technology. [0003] In order to solve this problem, the industry has recently ...
