Pixel circuit and display device

摘要

A pixel circuit includes: a switching transistor whose conduction is controlled by a drive signal supplied to the control terminal; a drive wiring adapted to propagate the drive signal; and a data wiring adapted to propagate a data signal. The drive wiring is formed on a first wiring layer and connected to the control terminal of the switching transistor. The data wiring is formed on a second wiring layer and connected to a first terminal of the switching transistor. A multi-layered wiring structure is used so that the second wiring layer is formed on a layer different from that on which the first wiring layer is formed.

1. A display device having a multi-layer wiring structure, comprising:
a plurality of pixel circuits; a first wiring configured to propagate a control voltage; and a second wiring configured to propagate a predetermined voltage,wherein at least one of the plurality of pixel circuits includes:
an electro-optical 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;and wherein the first wiring is formed on a first layer, the second wiring is formed on a second layer, and a first intermediate wiring that does not intersect with any wiring formed on the second layer is formed on a third layer which is different from the first and the second layers, the first intermediate wiring being electrically connected between the first current terminal and the second wiring.
