Embodiment Construction

[0013] Those skilled in the art can understand the creation by referring to the following detailed description and at the same time in conjunction with the accompanying drawings. Part of a cholesteric liquid crystal display, and certain elements in the accompanying drawings are not drawn to scale. In addition, the quantity and size of each component in the figure are only for illustration, and are not used to limit the scope of this creation.

[0014] It will be understood that when an element or film is referred to as being "on" or "connected to" another element or film, it can be directly on or directly connected to the other element or film To another element or film layer, or there is an intervening element or film layer between the two. In contrast, when an element is referred to as being “directly on” or “directly connected to” another element or layer, there are no intervening elements or layers present.

[0015] It should be noted that in the following embodiments, w...

Abstract

A cholesterol liquid crystal display comprises a first substrate, a second substrate, a cholesterol liquid crystal layer, a switching element, an insulating layer and a patterned low-reflection metal conductive layer. The second substrate is arranged opposite to the first substrate. The cholesterol liquid crystal layer is arranged between the first substrate and the second substrate. The switching element is disposed on the inner surface of the first substrate, the insulating layer is disposed on the switching element, and the patterned low-reflection metal conductive layer is disposed on the inner surface of the first substrate. A part of the low-reflection metal conductive layer is electrically connected to the switching element, and the low-reflection metal conductive layer has low light transmittance.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a cholesteric liquid crystal display. Background technique [0002] The reflective liquid crystal display has the advantages of thinness, lightness, and low power consumption because it does not need a backlight module to provide a light source. At present, many electronic products such as electronic papers or tablet PCs have products using reflective liquid crystal displays. Among them, cholesteric liquid crystals are suitable for reflective liquid crystal displays and can further achieve power saving because they can selectively reflect light in a part of the wavelength range and at the same time have the characteristics of showing a bistable state when no voltage is applied. Effect. [0003] When a cholesteric liquid crystal display is in a dark state, part of the light will pass through the cholesteric liquid crystal or be scattered inside the display. However, these light rays ...
