Abstract

The invention provides a color film substrate which comprises a color film layer, a phase difference layer and a first wire grating polarizer which are sequentially laminated. The phase difference layer comprises a plurality of first phase shift structures and second phase shift structures which are arranged alternately. The phase difference layer enables P light passing the phase shift structures and P light passing the second phase shift to generate a phase difference, and thus a P light reflecting effect can be reduced. Meanwhile, S light passing the phase difference layer and the first wire grating polarizer has no phase difference, and thus brightness of the S light is not affected. In addition, the invention further provides a display panel to which the color film substrate is applied and a corresponding display device. The display panel and the display device have the advantages of reducing a light reflection effect and not affecting display brightness.

Description

technical field [0001] The present invention relates to the field of display technology. Specifically, the present invention relates to a color filter substrate, and also relates to a display panel and a display device using the color filter substrate. Background technique [0002] WGP (wire grid polarizer, that is, wire grid polarizer) is currently widely used in the display field, and its structure is as follows figure 1 As shown, the wire grid adopts metal materials with high conductivity, such as Al. The wire grid of the wire grid polarizer adopts slit distribution, that is, gaps are formed between adjacent wire grids. Usually, the width of the wire grid is about 50 nm, the width of the slot is about 50 nm, and the height of the wire grid is about 150 nm. The light splitting principle of the wire grid polarizer is: when the external natural light (which can be considered as a combination of orthogonal light in the plane perpendicular to the propagation direction) irradi...
