Disclosed herein is a liquid crystal display including a pair of substrates, a liquid crystal layer sandwiched between the substrates, a pixel having a transmissive display region for displaying with transmitted light and a reflective display region for displaying with reflected light, a drive element for driving the pixel, a signal line for supplying a display signal to the drive element, and a gate line for supplying a scan signal to the drive element. One of the substrates includes an insulating planarization layer for planarizing a step produced by the signal line and/or the gate line, and a transparent electrode formed on the insulating planarization layer in the transmissive display region. With this structure, the leakage of light in the black display state can be prevented to thereby improve the contrast, and the transmissive display region can be enlarged to thereby ensure a high transmissivity.
