Abstract:
A display device comprising:a pair of substrates; a liquid crystal provided between said substrates; a pixel having a pair of first and second electrodes holding said liquid crystal therebetween, a first thin film transistor provided in said pixel and connected to said first electrode at one of source region and drain region thereof; a second thin film transistor provided in said pixel and connected to said second electrode at one of source region and drain region thereof; an image write signal line connected to the other of the source region and the drain region of said first thin film transistor; a reference potential line connected to the other of the source region and the drain region of said second thin film transistor; a gate line connected to a gate electrode of said first thin film transistor and connected to a gate electrode of said second thin film transistor, wherein a voltage having single polarity is applied between said first and second electrodes by applying an image write signal to said first electrode and setting said second electrode to a reference potential, and wherein said first and second electrodes are provided over one of said substrates to effect the application of said voltage in a in-plane switching mode.
