Patent ID: 8508496

Claim:
A liquid crystal display (LCD) with a built-in touch panel, comprising: an LCD unit, comprising: a lower substrate; an upper substrate, disposed opposite to the lower substrate; a liquid crystal layer, disposed between the lower substrate and the upper substrate; a first polarized plate, disposed on the lower substrate; a touch panel, disposed opposite to the upper substrate; a second polarized plate, disposed at a side of the touch panel facing to the LCD unit, and located between the LCD unit and the touch panel; and an air layer configured between the upper substrate and the second polarized plate and an airtight gasket disposed at a periphery of the air layer surrounding the air layer, wherein the first polarized plate and the second polarized plate are the only polarizing plates in the liquid crystal display (LCD) with a built-in touch panel, the first polarized plate has a first polarized direction, and the second polarized plate has a second polarized direction, and the first polarized direction is matched with the second polarized direction for displaying an image and preventing light reflection.
