Display substrate and method for manufacturing the same, display panel and display device
First Claim
1. A display substrate, comprising a base substrate, wherein at least two refractive layers are provided on the base substrate, and a gate electrode is provided on the refractive layers,wherein a refractive index of one of two adjacent refractive layers close to the base substrate is less than a refractive index of the other of two adjacent refractive layers away from the base substrate, and thicknesses of the refractive layers are nλ
- +λ
/4, where λ
is a wavelength of incident light, and n is a nonnegative integer, thereby reflective light rays are superposed on each other, generating a light counteraction effect and reducing reflectance,wherein the other of two adjacent refractive layers is directly located on the one of two adjacent refractive layers, andwherein refractive indexes of the at least two refractive layers gradually increase along a direction from the refractive layer close to the base substrate to the refractive layer away from the base substrate.

Abstract
A display substrate, a method for manufacturing the display substrate, a display panel and a display device are disclosed. The display substrate includes a base substrate. At least two refractive layers are provided on the base substrate, and a gate electrode is provided on the refractive layers. A refractive index of the refractive layer of two adjacent refractive layers close to the base substrate is less than a refractive index of the refractive layer of two adjacent refractive layers away from the base substrate, and thicknesses of the refractive layers are nλ+λ/4, where λ is a wavelength of incident light, and n is a nonnegative integer.
