Abstract

The invention provides a transflective liquid crystal display (LCD) device, comprising: a first substrate; a second substrate opposite to the first one; a liquid crystal layer which is located between the two substrates and whose liquid crystal molecules are horizontally aligned; a common electrode arranged on the first substrate; a transmission electrode and a reflection electrode arranged in turn on the second substrate; a first delay piece and a first polarizing plate arranged in turn on one side of the first substrate apart from the liquid crystal layer; a second delay piece and a second polarizing plate arranged in turn on one side of the second substrate apart from the liquid crystal layer; and a disc liquid crystal molecular membrane located between the first delay piece and the first substrate.

Description

【Technical field】 [0001] The 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 have the characteristics of low radiation, light, thin and small, and low power consumption, so they are widely used, and with the maturity and innovation of related technologies, their types are also becoming more and more diverse. [0003] Liquid crystal display devices can be classified into transmissive liquid crystal display devices, reflective liquid crystal display devices and transflective liquid crystal display devices according to different light sources used. The transmissive liquid crystal display device must have 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 d...
