    摘要: A level converter circuit includes an input terminal adapted to be supplied with a signal swinging from a first voltage to a second voltage lower than the first voltage; a first transistor having a gate electrode connected to the input terminal, and a source electrode connected to ground potential; a second transistor having a gate electrode connected to a drain electrode of the first transistor, a source electrode connected to a supply voltage, and a drain electrode connected to an output terminal; a load circuit connected between the gate electrode of the second transistor and the supply voltage; a third transistor having a source electrode connected to the input terminal, a drain electrode connected to the output terminal, and a gate electrode supplied with a DC voltage higher than the second voltage and lower than the first voltage. The level converter circuit outputs a third voltage higher than the second voltage when the input terminal is supplied with the first voltage, and the level converter circuit outputs the second voltage when the input terminal is supplied with the second voltage.

    摘要: 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 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 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 delay direction and width of a timing to output the data signal, and a setting for rising and falling of an internal control signal.
