Abstract

See full text

A double-layer cholesteric liquid crystal display and its manufacturing method are disclosed. The double-layer cholesteric liquid crystal display includes three transparent substrates, two opposing electrode layers, two cholesteric liquid crystal layers, and a first light-absorbing layer. Additionally, the double-layer cholesteric liquid crystal display incorporates two drive ICs and a second light-absorbing layer. The two drive ICs can be positioned either on the same side or on opposite sides within the non-display area of the double-layer cholesteric liquid crystal display. Furthermore, the first cholesteric liquid crystal layer exhibits a first color light, and the second cholesteric liquid crystal layer exhibits a second color light, where the colors are selected as contrasting colors. Additionally, the two cholesteric liquid crystal layers possess mutually opposite optical rotary properties. The invention is capable of producing a thinner, lighter double-layer cholesteric liquid crystal display that enhances contrast and reflectivity, thereby effectively improving the overall display performance.
