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 region and a peripheral region surrounding the central region, wherein the peripheral region comprises at least one annular sub-region gradually extending from the edge of the display panel to the center of the display panel. Due to the fact that in each annular sub-region, first alignment films corresponding to preset sub-pixels are smaller than first alignment films corresponding to other sub-pixels except the preset sub-pixels in alignment angle and / or second alignment films corresponding to the preset sub-pixels are smaller than second alignment films corresponding to other sub-pixels except the preset sub-pixels in alignment angle, the light penetration rates of the regions corresponding to the preset sub-pixels are smaller than those of the regions corresponding to the other sub-pixels, and further the problem of edge color shifting of the display panel due to the fact that light of a certain color of the edge of a backlight module is more than the light of other colors is solved.
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...
