Abstract

The invention discloses a liquid crystal display panel and a preparation method thereof. The liquid crystal display panel comprises a first substrate, wherein a first color resistance layer is configured on the first substrate; a second substrate, wherein the second substrate and the first substrate are arranged in a paired mode, and a second color resistance layer is arranged on the second substrate; and a polymer network liquid crystal layer, which is arranged between the first substrate and the second substrate, wherein the first color resistance layer comprises a plurality of first color sub-resistors, and the second color resistance layer comprises a plurality of second color sub-resistors which are respectively arranged corresponding to the plurality of first color sub-resistors in the first color resistance layer in color and position. When the polymer network liquid crystal is in a scattering mode, the absorption effect of the color films with different colors in the adjacent sub-pixels on scattered light of the adjacent sub-pixels is utilized, the dark state light leakage degree is reduced, and therefore the contrast ratio is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal display panel and a preparation method thereof. Background technique [0002] With the development of display technology, various emerging technologies continue to emerge and enrich various new display application scenarios. Among them, transparent display can be used in goods display cabinets, electronic bulletin boards, head-up displays and other fields, and has received extensive attention. At present, there are two main technical routes for realizing transparent display. One is the traditional liquid crystal display panel, which improves its transmittance through the design of red, green, blue and white pixels, but the transmittance is still low (less than 20%); The first is to use active light-emitting technologies such as OLEDs. This technology has a high transmittance, but its defects in contrast and brightness greatly limit its application. ...
