ABSTRACT:
A liquid crystal display device having a pair of substrates with a display medium interposed therebetween, includes: a plurality of scanning lines and a plurality of data lines provided on one of the pair or substrates so as to cross each other; a plurality of switching elements, each of the switching elements being connected with one of the scanning lines and one of the data lines; an insulating layer provided so as to cover the plurality of scanning lines, the plurality of data lines, and the plurality of switching elements; a plurality of pixel electrodes provided on the insulating layer, each of the pixel electrodes partially overlapping at least one scanning line and at least one data line; and a plurality of contact holes formed in the insulating layer, through each of which an output terminal of a respective switching element and a respective pixel electrode are connected. The display medium contains a liquid crystal material, and liquid crystal molecules of the liquid crystal material are oriented in at least two directions on at least one of the pair of substrates.
