Abstract
A display housing a sound element and a driving circuit that may be built in on the same substrate as the display panel. Thin-film transistors PTFT constituting pixels and a sound wave generation device SPO1 having a laminated structure of a heat generation layer 700, a heat insulation layer 701 and a heat radiation layer 702 are formed on a thin-film transistor (TFT) substrate 500 on which polysilicon thin-film transistors PTFT are formed.
