Embodiment Construction

[0014] Such as Figure 4 As shown, a reflective liquid crystal display 100 disclosed in a preferred embodiment includes a polarizer 110 , a first compensation film 120 , a second compensation film 130 , a liquid crystal unit 140 and a reflection unit 150 . The first compensation film 120 and the second compensation film 130 are located between the polarizer 110 and the liquid crystal unit 140 to compensate the display viewing angle of the liquid crystal unit 140 . Wherein, both the first compensation film 120 and the second compensation film 130 are negative uniaxial compensation films, that is, the refractive index of the o light is greater than that of the e light. The liquid crystal molecules of the liquid crystal unit 140 are all positive uniaxial molecules, that is, the refractive index of the e-ray is greater than that of the o-ray.

[0015] The liquid crystal unit 140 includes a first conductive glass 141 , a second conductive glass 142 , a first alignment film 143 , a...

Abstract

The present invention provides a reflective lcd, including a polarizer, a first compensation film and a liquid crystal unit. The liquid crystal unit includes a first liquid crystal molecule which long axis is vertical to the polarizer. The first compensation film is provided between the polarizer and the liquid crystal unit, compensating the phase delay of the linearly polarized light beam caused by the first liquid crystal molecule. The reflective lcd adopts the first compensation film to compensate the phase delay of the linearly polarized light beam caused by the first liquid crystal molecule, reducing the generation of light leakage.

Description

technical field [0001] The invention relates to a reflective liquid crystal display, in particular to a reflective liquid crystal display capable of reducing light leakage. Background technique [0002] At present, liquid crystal display technology is becoming more and more mature, and liquid crystal displays occupy an increasing share in the display market. Typical liquid crystal displays mainly include transmissive liquid crystal displays and reflective liquid crystal displays. The transmissive liquid crystal display mainly uses a backlight module to provide the light source required for display, and then through the state change of the liquid crystal layer when power is applied, the light beam emitted by the light source is selectively transmitted to complete the display operation. The reflective liquid crystal display mainly uses a reflective film layer to reflect the ambient light passing through the liquid crystal layer, so as to complete the display operation. [00...
