Embodiment Construction

[0025] 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 111 located between the two substrates 22, 21, the liquid crystal layer 111 includes a plurality of positive liquid crystal molecules.

[0026] A first upper retarder 52 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 disposed on the inner surface of the upper substrate 22 . The common electrode 221 is made of a transparent conductive material, such as indium tin oxide (ITO) or indium zinc oxide (IZO).

[0027] The liquid crystal molecules of the liquid crystal layer are hybrid alignment (Hybrid Alignment), that is...

Abstract

The semi-penetrating semi-reflecting liquid crystal display device includes an upper baseplate, a lower baseplate, a liquid crystal layer positioned between said upper baseplate and said lower baseplate, a common electrode placed on upper baseplate, pixel electrode formed on lower baseplate, said pixel electrode, common electrode and liquid crystal layer positioned between them are formed into several pixel regions, every pixel region has a reflecting region electrode and a penetrating region electrode. Said invention also provides the concrete structure of said liquid crystal layer. Said liquid crystal display device has the characteristics of high contrast and good viewing angle.

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...
