Embodiment Construction

[0051] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0052] Such as Figure 1 to Figure 5 As shown, the embodiment of the present invention provides a transflective blue-phase liquid crystal display panel, including a first substrate 100, a second substrate 200 opposite to the first substrate 100, and a second substrate 200 disposed between the first substrate 100 and the second substrate. The liquid crystal layer between the substrates 200, the liquid crystal layer is a blue phase liquid crystal layer;

[0053] Wherein, the first substrate 100 and the second substrate 200 include several sub-pixels, and each sub-pixel includes a reflection area and a transmission area;

[0054] The thickness of the liquid crystal cell in the reflective area and the transmissive area is equal;

[0055] The part of the se...

Abstract

The present invention provides a transflective blue-phase liquid crystal display panel comprising a first substrate, a second substrate, and a liquid crystal layer, wherein the first substrate and the second substrate comprise a plurality of subpixels, and each subpixel comprises a reflective region and a transmissive region, the liquid crystal cell gap of the reflective region is equal to that of the transmissive region, a plurality of first common electrodes and first pixel electrodes that are alternately arranged at equal intervals are set on the part of the second substrate; a second common electrode is set on the part of the first substrate, a second pixel electrode having a via hole at its center is set on the part of the second substrate. In the invention, an alignment layer can be omitted; the display visual angle can be enlarged by designing an electrode structure, and the contrast ratio can be improved, thereby a single cell-gap structure can be attained.

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...
