Patent ID: 8525760

Claim:
An electro-optical device comprising: a data line; a control line; and a unit circuit arranged corresponding to an intersection of the data line and the control line, the unit circuit including: a first transistor that includes a first semiconductor film; an electro-optical element electrically connected to one of a source or a drain of the first transistor; a second transistor that includes a second semiconductor film, the second transistor connected between the one of the source or the drain and a gate of the first transistor; a holding element that is connected to the gate of the first transistor and holds a gate voltage of the first transistor according to a data signal; and a wiring connected between the second transistor and the gate of the first transistor, the first transistor supplying a current based on the gate voltage to the electro-optical element, the wiring being formed in a layer which is different from a layer in which the first semiconductor film and the second semiconductor film are formed, the wiring having a portion formed in the layer different from a gate layer in which the gate of the first transistor is formed, the portion crossing the control line.
