Abstract

A color filter substrate, a display panel and a display apparatus containing the color filter substrate are provided. The color filter substrate includes a color filter layer, a phase difference layer and a first wire grid polarizer arranged in sequence, the phase difference layer including a plurality of first phase shift structures and a plurality of second phase shift structures arranged alternately, the phase difference layer allowing P light that passes through the first phase shift structures and P light that passes through the second phase shift structures to have a phase difference.

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...
