Abstract

There is a need for decreasing a variation in times for writing to TFT elements for pixels in a direction along the extension of a gate line in a liquid crystal display apparatus. A display apparatus includes a display panel having multiple gate lines and multiple drain lines arranged in a matrix and a data driver for outputting a display data signal to each drain line. The data driver includes: an internal control signal generation circuit for generating an internal control signal for setting a timing to output a data signal to a drain line of each block on a block basis by dividing the plurality of drain lines into multiple blocks; and a register circuit for recording a setting for division of the block, a setting for a delay direction and a delay width of a timing to output the data signal, and a setting for rising and falling of an internal control signal.
