Display apparatus and method of driving the same

A display apparatus, comprising:

• a pixel array substrate;
• and
• an opposite substrate arranged opposite to said pixel array substrate, on which an opposite electrode is formed,
• wherein said pixel array substrate includes:
• signal lines and scanning lines which are arrayed;
• display pixels formed in vicinity of said signal lines and scanning lines;
• a gradation voltage generating circuit which generates gradation voltages for supplying to said signal lines by performing resistance division by a plurality of resistor elements with regard to two types of reference voltages;
• a γ correction voltage generating circuit which generates a voltage for γ correction applied to at least one of connection paths between said plurality of resistor elements;
• and
• a signal line voltage generating circuit which selects the gradation voltage in accordance with digital pixel data among the gradation voltages generated by said gradation voltage generating circuit and supplies the selected gradation voltage to the corresponding signal line.

A driving method of a display apparatus comprising signal lines and scanning lines which are arrayed, and display pixels formed in vicinity of intersections of said signal lines and said scanning lines, comprising:

• generating gradation voltages for supplying to said signal lines by performing resistance division by a plurality of resistor elements with regard to two types of reference voltages;
• generating a voltage for γ correction applied to at least one connection path between said plurality of resistor elements;
• and
• selecting the gradation voltage in accordance with digital pixel data among the generated gradation voltages, and supplying the selected gradation voltage to the corresponding signal line.
