Abstract

The invention provides a display panel which comprises a first substrate, a second substrate and a liquid crystal layer. The first substrate and the second substrate are opposite to each other, and the liquid crystal layer is arranged between the first substrate and the second substrate; the display panel is divided into a plurality of pixel units, each pixel unit comprises at least one pixel, a first black matrix layer is arranged on the first substrate, a second black matrix layer is arranged on the second substrate; portions, which correspond to the pixels, of the first black matrix layer comprise shading portions and transmittance portions, the transmittance portions encircle the shading portions, and light transmission holes are formed in regions, which correspond to the shading portions, of the second black matrix layer; projection of the shading portions on the second black matrix layer covers the light transmission holes; electrode layers are arranged on at least one of the first substrate and the second substrate and are used for generating electric fields in the liquid crystal layer, and the electric fields of the various pixel units can be independently controlled. The invention further provides a display device correspondingly. The display panel and the display device have the advantages that contents can be displayed without polarizers, and accordingly light loss can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Traditional liquid crystal display devices such as figure 1 As shown, it includes a backlight module 20 and a display panel 10. The display panel 10 includes an array substrate 11, a color filter substrate 12 and a liquid crystal layer 13 between them. The outer sides of the array substrate 11 and the color filter substrate 12 are respectively provided with Two polarizers (upper polarizer 14 and lower polarizer 15 ) whose polarization directions are perpendicular to each other. A lower electrode 16 is arranged on the array substrate 11 , and an upper electrode 17 is arranged on the color filter substrate 12 , and an electric field for driving liquid crystal deflection is generated between the upper electrode 17 and the lower electrode 16 . When displaying, the lower polarizer 15 converts the natural li...
