An integrated circuit device includes a RAM block including a plurality of wordlines WL, a plurality of bitlines BL, a plurality of memory cells MC, wordline control circuit, and a data read control circuit, and a data line driver block which drives a plurality of data line groups of a display panel based on data supplied from the RAM block. The data read control circuit reads data for pixels corresponding to the signal lines by N (N is an integer larger than one) times reading in one horizontal scan period 1 H of the display panel. The data line driver block includes first to N-th divided data line driver blocks, each of which drives a different data line group of the data line groups and is disposed along a first direction X in which the bitlines BL extend.
