Patent ID: 8730134

Claim:
A display device having a multi-layer wiring structure, comprising: a plurality of pixel circuits; a first circuitry configured to output a control voltage onto a first wiring; and a second circuitry configured to output a predetermined voltage onto a second wiring, wherein at least one of the plurality of pixel circuits includes: a light-emitting element; a switching transistor including a control terminal and a first current terminal, the control terminal electrically connected to the first wiring, and the first current terminal electrically connected to the second wiring; a capacitive element electrically connected to the switching transistor so as to receive a voltage dependent on the predetermined voltage via the switching transistor; a driving transistor coupled to the capacitive element, and configured to provide a driving current to the electro-optical element; a first intermediate wiring electrically connected between the first current terminal and the second wiring, and wherein the first wiring is formed on a first layer, the second wiring is formed on a second layer, and the first intermediate wiring is formed on a third layer which is different from the first and the second layers.
