Abstract
A liquid crystal display device including: a display section including a liquid crystal layer; a pair of substrates interposing the liquid crystal layer; a plurality of pixel electrodes located in a matrix on one of the pair of substrates; a plurality of first thin film transistors respectively connected to the plurality of pixel electrodes; and a peripheral driving circuit located for driving the display section, the peripheral driving circuit being located on the substrate on which the first thin film transistors are located and having a second thin film transistor. Each of the first thin film transistors includes a first channel layer formed of a first crystalline silicon layer, and the second thin film transistor includes a second channel layer formed of a second crystalline silicon layer having a higher mobility than the mobility of the first crystalline silicon layer. The second crystalline silicon layer includes a catalytic element for promoting crystallization.
