Problems solved by technology

Although the multi-domain vertical alignment liquid crystal display has the effect of wide viewing angle, the gamma (gamma) curve will deviate when viewed from the side with a large viewing angle, resulting in color shift and affecting the viewing effect
[0003] Therefore, there is a technical problem of large viewing angle deviation in the existing liquid crystal display and needs to be solved.

Embodiment Construction

[0030] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments that the present application can be used to implement. The directional terms mentioned in this application, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are for reference only The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the application, but not to limit the application. In the figures, structurally similar elements are denoted by the same reference numerals. In the drawings, the thicknesses of some layers and regions are exaggerated for clear understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited thereto.

[0031] In view of the problem of large viewing angle deviation in the existing liquid crystal display...

Abstract

The invention provides a display panel and a display device. The display panel comprises red sub-pixels, green sub-pixels and blue sub-pixels which are sequentially arranged, and the number of display domain areas of the blue sub-pixels is larger than the number of display domain areas of the red sub-pixels and larger than the number of display domain areas of the green sub-pixels; differentiated design of the blue sub-pixels is carried out, and the red sub-pixels and the green sub-pixels keep the existing design, so that on the premise of ensuring the penetration rate, the ratio of emergent light of the blue sub-pixels in a display picture in a large viewing angle can be reduced, and the problem of large viewing angle color cast of an existing liquid crystal display is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of liquid crystal display (Liquid Crystal Display, LCD) technology, high transmittance and large viewing angle have become the development trend of liquid crystal display devices. How to improve the transmittance and viewing angle has become one of the important directions for future development. Currently, there are various liquid crystal displays with wide viewing angles on the market, such as in-plane switching (IPS) liquid crystal displays, multi-domain vertical alignment (MVA) liquid crystal displays, and the like. The multi-domain vertical alignment liquid crystal display divides a sub-pixel into multiple domains. When power is applied, the liquid crystal molecules are tilted in different directions, so that the observation effects in different directions tend to be consisten...
