Abstract

The invention provides a semi-transparent and semi-reflective blue-phase liquid-crystal display panel and a liquid-crystal display device. The liquid-crystal display panel comprises a first substrate, a second substrate opposite to the first substrate, and a liquid-crystal layer arranged between the first substrate and the second substrate; the first substrate and the second substrate comprise a plurality of sub-pixels, and each sub-pixel comprises a reflection zone and a transmission zone; the liquid-crystal layer is a blue-phase liquid-crystal layer; the thickness of the liquid-crystal boxes of the reflection zones and the thickness of the liquid-crystal boxes of the transmission zones are equal; a plurality of first common electrodes and first pixel electrodes alternatively arranged at an equal distance are arranged in the part of the second substrate corresponding to the transmission zones; and a second common electrode corresponding to the whole reflection zones is arranged in the part of the first substrate corresponding to the reflection zones, a second pixel electrode corresponding to the reflection zones is arranged in the part of the second substrate corresponding to the reflection zones, and a hollow hole is formed in the center of the second pixel electrode. According to the liquid-crystal display panel and the liquid-crystal display device, an alignment layer is eliminated; and according to the design of the electrode structure in the transmission zones and the reflection zones, a display visual angle is enlarged, a contrast ratio is improved, and the structure of a single-box thickness is realized.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a semi-transparent and semi-reflective blue-phase liquid crystal display panel and a liquid crystal display device. Background technique [0002] A liquid crystal display panel is generally formed by pairing a color filter substrate and an array substrate, and a liquid crystal layer is encapsulated in the space between the two substrates. Since the liquid crystal molecules themselves do not emit light, the display needs a light source to display images. According to the type of light source used, liquid crystal displays can be divided into transmissive, reflective and transflective. [0003] Among them, the transmissive liquid crystal display mainly uses the backlight as the light source, and the backlight is arranged behind the liquid crystal panel, and the pixel electrodes on the array substrate are transparent electrodes as the transmission area, which is benef...
