Embodiment

[0061] The liquid crystal display of the present invention is such as figure 1 As shown, it includes an upper substrate, an upper conductive layer, an upper alignment layer and a lower substrate, a lower conductive layer and a lower alignment layer that are attached to each other, and a layer of blue dye liquid crystal with chiral agent is poured between the upper and lower alignment layers. The inner surfaces of the upper substrate and the lower substrate are respectively provided with an ITO conductive layer, coated with a vertically-oriented alignment layer, and rubbed to realize the control of the liquid crystal orientation; under the liquid crystal cell, an orange reflection with a color complementary to the color of the dye is matched paper.

[0062] When no power is applied, the device is in a non-working state, and natural light enters the upper substrate from the outside, passes through the upper conductive layer, upper alignment layer, liquid crystal material, lower alig...

Abstract

The invention provides a reflection type liquid crystal display device. The reflection type liquid crystal display device comprises an upper substrate, a lower substrate, an upper orientation layer, a lower orientation layer, a liquid crystal composition and a reflecting material, wherein the liquid crystal composition is clamped between two orientation layers and comprises dye, a liquid crystal compound and a chiral agent, the reflecting material is located on the outer surface of the lower substrate, and the color of the liquid crystal composition is complementary with the color of the reflecting material. The invention provides a novel reflection type display mode. Dye-doped liquid crystals are used for displaying, usage of polaroids is abandoned, and the problem of the low reflectivity is fundamentally solved. Simultaneously, polaroids are not used, and brightness enhancement films are not required to be used for improving the reflectivity, so that the cost is reduced greatly. According to the reflection type liquid crystal display device, dye-doped liquid crystals are arranged between the upper substrate and the lower substrate, polaroids which are attached to surfaces of transparent substrates of traditional ordinary liquid crystal displayers are removed, the structure is simple, simultaneously, the light utilization ratio is greatly improved, and the reflection type liquid crystal display device has the advantages of being high in reflectivity, capable of achieving full-view display, low in cost and simple to produce and manufacture.

Description

Technical field [0001] The present invention relates to a liquid crystal display device, in particular to a reflective liquid crystal display device added with a dye and a chiral agent. Background technique [0002] With the development of science and technology and the improvement of life quality, information products have penetrated into all areas of our lives. The liquid crystal display is widely welcomed by the market because of its small size, no radiation, power saving, and no flicker. After decades of development, its technology has become very mature. In addition to large-scale TVs, computers, and portable mobile phones, more and more white goods have also introduced LCD displays. [0003] For example, rice cookers, the rice cookers on the market now use a liquid crystal display to display the functions, working status, countdown and other information of the rice cooker, all at a glance. In order to match the overall appearance of the product, this type of display general...
