Patent ID: 7310093

Claim:
An electro-optical apparatus, comprising: pixel circuits disposed at intersections of a plurality of scanning lines and a plurality of data lines; a scanning-line drive circuit that selects the scanning lines; a data-line drive circuit, the pixel circuits having a plurality of types of pixel circuits corresponding to a plurality of primary colors, the data-line drive circuit being provided corresponding to the primary colors, and having a current generating circuit that supplies a current to a corresponding data line, the current generating circuit comprising: a power supply terminal having a power supply voltage applied thereto; a first resistor and a second resistor, one end of each of the first resistor and the second resistor being coupled to the power supply terminal, and a resistance of the first resistor and a resistance of the second resistor being different; a first transistor that allows a current corresponding to a voltage of a gate of the first transistor to flow between a first terminal and a second terminal of the first transistor, the first terminal being coupled to another end of the first resistor, and the second terminal and the gate being coupled with each other; and a second transistor that allows a current corresponding to a voltage of a gate of the second transistor to flow between a first terminal and a second terminal of the second transistor, the first terminal being coupled to another end of the second resistor, and the gate of the second transistor being coupled to the gate of the first transistor; and the electro-optical apparatus further comprising a setting circuit that sets individually a resistance of at least one of the first resistor and the second resistor for each of the primary color.
