Patent attributes
In one embodiment, a liquid crystal display device having a plurality of pixels includes a first substrate having an insulating substrate, a first detection element extending in a first direction above the insulating substrate, a second detection element extending in a second direction crossing the first direction and an insulating film provided between the first and second detection circuits. A second substrate is arranged opposing to the first substrate so as to hold a liquid crystal layer therebetween. A detection circuit is provided on the first substrate to detect change of electrostatic capacitance between the first and second detection elements. At least one of the first and second detection elements is an element required for operating the liquid crystal layer.
