Patent ID: 7038642

Claim:
A display device comprising: a display region comprising a plurality of display pixels; a peripheral driving circuit that supplies a driving signal to each of the display pixels and is disposed outside the display region; a thin film transistor disposed for each of the display pixels; a pixel electrode disposed for each of the display pixels, a pixel voltage being applied to the pixel electrode through the corresponding thin film transistor; a light-blocking layer disposed under each of the thin film transistors; a first insulating layer having the light-blocking layers therein; and a storage capacitance element disposed for each of the display pixels, the storage capacitance element comprising a first electrode disposed in a second insulating layer located above an active layer of the corresponding thin film transistor and a second electrode disposed in the first insulating layer, wherein the peripheral driving circuit comprises a plurality of insulating layers each including metal wiring therein, and the peripheral driving circuit includes the first insulating layer of the light-blocking layers and the second insulating layer of the first electrode as two of the insulating layers of the peripheral driving circuit.
