Problems solved by technology

Usually, in order to ensure the pixel aperture ratio and pixel transmittance, the junction of the two domain regions is usually shielded by a non-resin light-blocking layer or a metal opaque layer, which makes the black in the junction area of ​​the two domain regions The brightness of the white state is improved, but it does not contribute to the white state, resulting in a low contrast ratio of the LCD

Embodiment Construction

[0031] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises a first substrate and a second substrate which are oppositely arranged, a plurality of sub-pixel regions and first electrodes located inside the sub-pixel regions. The first electrodes include first sub-electrodes, second sub-electrodes and third sub-electrodes.The sub-pixel regions include a first domain region, a domain boundary region and a second domain region which are sequentially arranged in the second direction, the width of the domain boundary region is A, a black matrix comprises a first black matrix, the orthographic projection of the first black matrix in the plane where the first substrate is located and the domain boundary region are overlapped, the width of the first black matrix is B, B is larger than or equal to B1 and smaller than or equal to B2, B1 is equal to -1.48+0.95A, and B2=-3.04+1.28A. According to the scheme, the contrast ratio of the display panel and the display device is increased, and the display performance of the display panel and the display device of the dual-domain structure is improved.

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] IPS (In-Plane Switching, in-plane switching) mode and FFS (Fringe Field Switching, fringe field switching) mode liquid crystal display provide a liquid crystal device structure with a wide viewing angle, and the pixel electrode and the common electrode are arranged on the same substrate. The liquid crystal is driven by generating a transverse electric field force to change the orientation angle of the optical axis of the liquid crystal molecules in a plane parallel to the substrate. Among them, the single domain (one domain) technology in IPS and FFS modes is widely used due to its advantages of wide viewing angle, small color shift, and low power consumption. However, as users have higher and higher requirements for display performance, defects such as angular deviation and poor contrast in single-d...
