Display driving apparatus and display apparatus comprising the same

A display apparatus that performs image display on the basis of display data, the apparatus comprising:

• a display panel having a display area in which display pixels are arrayed, the display panel having scanning lines arrayed in a row direction, signal lines arrayed in a column direction, and pixel electrodes near intersections between the scanning lines and the signal lines;
• a signal generating circuit that generates a driving signal for sequentially sets the display pixels corresponding to the respective scanning lines in a selected state, and applies a signal voltage corresponding to a gradation value of display data to a pixel electrode of each of the display pixels;
• and
• a correcting circuit that corrects the driving signal in accordance with selecting operation by the driving signal of each of the display pixels, and brings a magnitude of the signal voltage with respect to a gradation value of the display data, which is to be applied to the pixel electrode of each of the display pixels, close to the same value, and applies said corrected driving signal to each of the display pixels set in the selected state.
