Abstract

The embodiment of the invention provides a display panel and a preparation method thereof and a display device. The display panel comprises an array substrate, an opposite substrate and a liquid crystal layer, wherein the array substrate and the opposite substrate are oppositely arranged, the liquid crystal layer is arranged between the array substrate and the opposite substrate, a compensation layer is arranged on the array substrate or the opposite substrate, the included angle between the optical axis direction of the compensation layer and the initial optical axis direction of liquid crystal molecules in the liquid crystal layer is smaller than or equal to 10 degrees, the dispersion characteristics of the liquid crystal layer and the compensation layer are opposite, and the compensation layer is used for enabling the sum of the phase delay of light passing through the compensation layer and the phase delay of light passing through the liquid crystal layer to be integer multiples of the wavelength of the light. According to the invention, the dispersion characteristics of the liquid crystal layer and the compensation layer are opposite, and along with the increase of the light wavelength, the sum of the phase delay of light passing through the compensation layer and the phase delay of light passing through the liquid crystal layer is small in variation, so that the phase compensation effect of the compensation layer is guaranteed, the problems of dark-state light leakage and purple emission are effectively solved, and the color cast problem is effectively improved.

Description

technical field [0001] The present invention relates to but not limited to the field of display technology, and specifically relates to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Liquid Crystal Display (LCD for short) has the characteristics of small size, low power consumption, and no radiation, and has been developed rapidly in recent years. The main structure of the LCD includes a thin film transistor array (Thin Film Transistor, TFT for short) substrate and a color filter (CF for short) substrate of the cell (CELL), and liquid crystal (LC) molecules are filled in the array substrate and the color filter Between the substrates, an electric field for driving liquid crystal deflection is formed by controlling the common electrode and the pixel electrode to realize grayscale display. According to the display mode, LCD can be divided into: Twisted Nematic (TN for short) display mode, Vertical Alignment (VA for short) ...
