A liquid crystal display with a built-in touch panel includes an LCD unit, a touch panel and a second polarized plate. Each vibration attenuation member includes a top portion, a bottom portion defining a mounting hole, and two elastic portions. Pads are disposed in a peripheral region formed around the active region and the pads are electrically connected to the photodiode units. When the actuator is acted to push the slider moving along a first direction, the linkage mechanism is linked with the slider to push the card carrier in a second direction opposite to the first direction so that the card carrier and the electric card are removed from the insulating main body.
