Embodiment Construction
[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] The shapes and sizes of the components in the drawings do not reflect the real scale, but are only intended to schematically illustrate the content of the present invention.
[0020] As we all know, the liquid crystal display panel mainly controls the rotation of the liquid crystal by using the electric field between the pixel electrode and the common electrode, so as to control the transmittance of the liquid crystal. According ...

Abstract
The invention discloses a display panel and a display device. The display panel is divided into a central area and a peripheral area surrounding the central area. The peripheral area includes at least one annular sub-area gradually extending from the edge of the display panel to the center of the display panel; since each Within the ring sub-area, the default sub-area The alignment angle of the first alignment film corresponding to the pixel is smaller than the alignment angle of the first alignment film corresponding to the other sub-pixels except the preset sub-pixel; and / or the alignment angle of the second alignment film corresponding to the preset sub-pixel is smaller than the alignment angle of the second alignment film corresponding to the preset sub-pixel. Set the alignment angle of the second alignment film corresponding to other sub-pixels other than the sub-pixel. Therefore, the light transmittance of the area corresponding to the preset sub-pixel is smaller than the area corresponding to other sub-pixels, which is equivalent to making the light transmittance of the first color in the annular sub-region smaller than the light transmittance of other colors, and then It can compensate for the color cast problem at the edge of the display panel caused by the fact that the edge of the backlight module emits more light of a certain color than other colors.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Quantum Dots (QDs), also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. The particle size of quantum dots is generally between 1 and 20 nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure with molecular characteristics, and can emit fluorescence after being excited. And because quantum dots have a narrow Full Width at Half Maximum (FWHM) and almost no transmission of yellow light near the wavelength of 600nm, they can significantly improve the color saturation of the screen, so they have attracted widespread attention. [0003] At present, the relatively mature technology of the application of quantum dots is applied to the backlight. The quantum dot film layer is added to the backlight film, and the q...
