ABSTRACT:
An electro-optical apparatus includes scanning lines, data lines, and pixels in a pixel area, virtually divided into different regions. The electro-optical apparatus further includes a scanning-line driving circuit including a shift register, the scanning-line driving circuit selecting a scanning line included in one of the regions and then selecting a scanning line included in the other region, a block selection circuit for sequentially selecting a block composed of the data lines for m columns, a data-signal supplying circuit for supplying respective data signals having voltages according to grayscales of pixels, a sampling switch sampling the data signals, and a voltage measuring circuit for measuring a voltage of a data signal supplied to at least one of the m image signal lines in a period from a rising of the transfer start pulse to a supply of an image signal corresponding to the scanning line at a first row.
