Embodiment Construction

[0031] Figure 4 It is a schematic cross-sectional view of the first embodiment of the transflective liquid crystal display device of the present invention. The transflective liquid crystal display device 10 of the present invention includes an upper substrate 22, a lower substrate 21 opposite to the upper substrate 22, A liquid crystal layer 23 located between the two substrates 22, 21, the liquid crystal layer 23 includes a plurality of positive liquid crystal molecules (not shown).

[0032] The liquid crystal molecules in the liquid crystal layer 23 are homogeneously aligned with a pretilt angle of 0°-15°, and the liquid crystal molecules are roughly aligned horizontally under the action of the upper and lower alignment films 41 and 42 .

[0033] A first upper retarder 521 , a second upper retarder 522 , and an upper polarizer 32 are sequentially disposed on the outer surface of the upper substrate 22 . A common electrode 221 and an upper alignment film 42 are sequentially...

Abstract

The present invention relates to a semi-penetrating semi-reflecting liquid crystal device. It includes an upper baseplate, a lower baseplate, a liquid crystal layer positioned between said upper baseplate and said lower baseplate, an upper polarization plate placed on outside of upper baseplate, an upper regiospecific film placed between said liquid crystal layer and said upper baseplate, a common electrode placed on the upper baseplate, a lower regiospecific film placed between said liquid crystal layer and said lower baseplate, pixel electrode placed on lower baseplate, said pixel electrode, common electrode and liquid crystal layer positioned between them are formed into pixel region, said every pixel region has a reflecting region electrode and a penetrating region electrode, and a lower polarization plate placed on outside of lower baseplate. Said invention also provides the concrete structure of said liquid crystal layer.

Description

【Technical field】 [0001] The present invention relates to a liquid crystal display device, in particular to a semi-transmissive and semi-reflective liquid crystal display device. 【Background technique】 [0002] Liquid crystal display devices are widely used due to their characteristics of low radiation, light and thin size, and low power consumption. With the maturity and innovation of related technologies, there are more and more types of liquid crystal display devices. [0003] According to different light sources used by the liquid crystal display device, it can be divided into a transmissive liquid crystal display device and a reflective liquid crystal display device. The transmissive liquid crystal display device must install a backlight on the back of the liquid crystal display panel to realize image display, but the energy consumption of the backlight accounts for about half of the energy consumption of the entire transmissive liquid crystal display device, so the tra...
