Patent ID: 8625056

Claim:
A liquid crystal display, comprising: a first flat glass substrate, an opposite second flat glass substrate, and a liquid crystal layer sandwiched therebetween; a backlight module disposed adjacent to the first flat glass substrate; a color filter disposed between the first flat glass substrate and the backlight module; a bandpass filter member disposed on the second flat glass substrate, the bandpass filter member being configured for allowing a light of a given spectrum emitted from the backlight module to pass therethrough, and blocking light that is not in the given spectrum from passing therethrough; and a touch panel disposed adjacent to the bandpass filter member; wherein the bandpass filter member is further configured for allowing light of the given spectrum emitted from outside of the liquid crystal display to pass therethrough, and reflecting light emitted from outside of the liquid crystal display that is not in the given spectrum, such that when the backlight module is turned off, the light from outside of the liquid crystal display passes through the touch panel and reaches the bandpass filter member, and the bandpass filter member reflects the light that is not in the given spectrum so as to make the liquid crystal display achieve a mirror function.
