Abstract
The transmission type liquid crystal display device of this invention includes a pair of substrates and a liquid crystal layer interposed therebetween. One of the substrates includes: scanning lines and signal lines crossing each other; switching elements formed at crossings of the scanning lines and the signal lines; an insulating film of a light-transmitting organic material which cover the scanning lines and the signal lines and the switching elements; and pixel electrodes formed on the insulating film. The insulating layer has at least a polarizing property. The other substrate also includes a layer having at least the polarizing property. At least one of the layers having the polarizing property formed on the substrates is arranged inside of the liquid crystal display device.
