Abstract
A reflective type liquid crystal display apparatus includes: a first transmissive substrate; a second substrate disposed to face the first substrate; a liquid crystal layer interposed between the first substrate and the second substrate, the liquid crystal layer including a plurality of pixels; a plurality of reflective pixel electrodes, provided on the second substrate, for applying driving voltages to the pixels; a plurality of driving devices, provided on the second substrate, for driving the reflective pixel electrodes, respectively; and a plurality of protective devices disposed in the vicinity of the driving devices on the second substrate. The driving devices and the protective devices are disposed below the reflective pixel electrodes. Each of the driving devices and the protective devices includes an insulator, electric breakdown in each of the protective devices occurs prior to electric breakdown in a corresponding one of the driving devices, thereby reducing the potential difference of static electricity applied to the corresponding one of the driving devices.
