Abstract
A liquid crystal display (LCD) with a built-in touch panel includes an LCD unit, a touch panel and a second polarized plate. The LCD unit includes a lower substrate, an upper substrate, a liquid crystal layer and a first polarized plate. The upper substrate is disposed opposite to the lower substrate, and the liquid crystal layer is disposed between the lower substrate and the upper substrate. The first polarized plate is disposed on the lower substrate and has a first polarized direction. The touch panel is disposed opposite to the LCD unit. The second polarized plate having a second polarized direction is disposed on the touch panel and located between the LCD unit and the touch panel. An intensity of a reflected light occurred in the LCD with the built-in touch panel is relatively low, so that good contrast and visibility are obtained.
