Abstract

The invention provides a display panel and a preparation method thereof, belongs to the semi-reflecting and semi-transmitting display technical field, and can solve the problems that an existing semi-reflecting and semi-transmitting LCD device has dark state light leak problems, and is complex in preparation technology; each pixel of the display panel comprises a transmitting zone and a reflecting zone; the display panel comprises a first Polaroid, a first substrate, a first orientation layer, liquid crystal layers, a second orientation layer, a second substrate and a second Polaroid; a reflecting layer is arranged between the second orientation layer and the second Polaroid of the reflecting zone; the liquid crystal layer of the reflecting zone comprises a nematic liquid crystal and a polymer network; the liquid crystal layer of the transmitting zone comprises a liquid crystal mixture, or comprise a nematic liquid crystal and a polymer network; the polymer network is formed by polymerizing polymerisable monomers of the liquid crystal mixture; the liquid crystal mixture comprises the nematic liquid crystal and polymerisable monomers; under a non-electric filed condition, the orientation of the nematic liquid crystal in the reflecting zone is different from that of the first orientation layer, and the orientation of the nematic liquid crystal in the transmitting zone is same with that of the first orientation layer.

Description

technical field [0001] The invention belongs to the technical field of transflective and semitransparent liquid crystal displays, and in particular relates to a display panel and a preparation method thereof. Background technique [0002] There are mainly two types of liquid crystal display devices: transmissive and reflective. The former relies on the light of the backlight for display, so its light source is stable but consumes a lot of energy; the latter relies on ambient light for display, so its energy consumption is low, but the display The effect depends on the external environment. In order to combine the advantages of the two display modes, a transflective liquid crystal display device has been proposed, that is, each pixel includes a transmissive area and a reflective area at the same time. [0003] Obviously, the light in the transmission area only passes through the liquid crystal layer once, and the light in the reflection area passes through the liquid crystal...
