Embodiment Construction

[0021] 2 is a schematic cross-sectional view of the first embodiment of the liquid crystal display device of the present invention. The liquid crystal display device 2 of the present invention includes a lower substrate 29, an upper substrate 22 arranged opposite to the lower substrate 29, and an upper substrate 22 sandwiched between the two substrates 29, 22. The liquid crystal layer 200. The liquid crystal display device 2 is a transflective liquid crystal display device, and the twist angle of the liquid crystal molecules in the liquid crystal layer 200 is 90 degrees.

[0022] A half-transmitting semi-reflective layer 21, a polarizer 27, and an alignment film 25 are sequentially arranged on the inner surface of the lower substrate 29, and the lower substrate 29 further includes a plurality of thin film transistors (Thin Film Transistor, TFT) (not shown in the figure) ). A color filter 20 , a transparent common electrode 28 , a polarizer 24 and an alignment film 26 are sequ...

Abstract

A liquid crystal display device includes a first base plate, a second base plate, a LC layer between them, a transparent electrode on the first base plate, a semi-penetration semi-reflection layer formed on the second base plate and two diffusers set on the two base plates separately.

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] Portable electronic devices such as electronic watches, calculators, personal digital assistants (PDAs) and mobile phones mostly use liquid crystal display devices as their display devices. Display capabilities, and later used semi-transmissive and semi-reflective liquid crystal display devices. [0004] see figure 1 The prior art transflective liquid crystal display device 1 includes two parallel transparent lower substrates 19 and an upper substrate 12 , and a liquid crystal layer 100 is sandwic...
