Abstract: A liquid crystal display device that is not influenced by a noise in obtaining positional information can be provided. The liquid crystal display device includes a first substrate provided with a pixel electrode and a common electrode with a first insulating film interposed therebetween. The pixel electrode and the common electrode partly overlap with each other. The liquid crystal display device further includes a second substrate provided with a pair of electrodes, a resin film covering the pair of electrodes, and a conductive film on the resin film. The pair of electrodes partly overlap with each other with a second insulating film interposed therebetween. The liquid crystal display device further includes a liquid crystal layer between the conductive film on the second substrate side and the pixel electrode and the common electrode on the first substrate side. A predetermined potential is supplied to the conductive film.

Abstract: One object is to provide a method for manufacturing a display device in which shift of the threshold voltage of a thin film transistor including an oxide semiconductor layer can be suppressed even when ultraviolet light irradiation is performed in the process for manufacturing the display device. In the method for manufacturing a display device, ultraviolet light irradiation is performed at least once, a thin film transistor including an oxide semiconductor layer is used for a switching element, and heat treatment for repairing damage to the oxide semiconductor layer caused by the ultraviolet light irradiation is performed after all the steps of ultraviolet light irradiation are completed.
