Classification: CPC G | IPC G

Claim 6:
7. A method for preparing a display panel, comprising:
respectively preparing an array substrate and an opposite substrate, wherein a compensation layer are formed on the array substrate or the opposite substrate;
forming a liquid crystal layer between the array substrate and the opposite substrate;, wherein:
an included angle between an optical axis direction of the compensation layer and an initial optical axis direction of the liquid crystal molecules in the liquid crystal layer is less than or equal to 10 degrees, dispersion characteristics of the liquid crystal layer and the compensation layer are the opposite of each other, and the compensation layer is configured in such a way that the sum of a phase retardation of light passing through the compensation layer and a phase retardation of light passing through the liquid crystal layer is an integral multiple of a light wavelength;
preparing the array substrate comprises: forming an array structure layer on an array base substrate, and forming a first alignment layer on the array structure layer; and
preparing the opposite substrate, comprises: forming an opposite structure layer on an opposite base substrate, forming the compensation layer on the opposite structure layer, and forming a second alignment layer on the compensation layer; or, forming the compensation layer on the opposite base substrate, forming the opposite structure layer on the compensation layer, and forming a second alignment layer on the opposite structure layer;
the first alignment layer is configured to make the liquid crystal near the first alignment layer in the liquid crystal layer have a first initial posture, and the second alignment layer is configured to make the liquid crystal near the second alignment layer have a second initial posture; and the first alignment layer and the second alignment layer have a same rubbing direction, making the first initial posture and the second initial posture mirror symmetric with respect to the central horizontal plane of the liquid crystal layer; and
forming the compensation layer comprises:
forming a third alignment layer on the opposite base substrate or the opposite structure layer, and forming the compensation layer on the third alignment layer; and
the third alignment layer and the second alignment layer having a same rubbing direction, making a liquid crystal in the compensation layer having the same posture as the second initial posture.
