Display driver, electro-optical device, and electronic apparatus

A display driver configured to drive an electro-optical panel including a data line, the display driver comprising:

• a first D/A converter circuit configured to output a gradation voltage corresponding to upper-bit data of display data;
• a second D/A converter circuit configured to output a reference voltage corresponding to lower-bit data of the display data;
• and
• an inverting amplifier circuit configured to amplify the gradation voltage with reference to the reference voltage, and to drive the data line of the electro-optical panel, wherein
• the second D/A converter circuit includes
• a first resistor provided between a node of a high potential-side power source and an output node of the reference voltage,
• a second resistor provided between the output node and a first node,
• a reference voltage ladder resistance circuit provided between the first node and a node of a low potential-side power source, and
• a switch circuit including a plurality of switch elements provided between a plurality of output taps of the reference voltage ladder resistance circuit and the node of the low potential-side power source, the plurality of switch elements being turned on or off in accordance with the lower-bit data.
