PURPOSE: To provide a display driving circuit and a display device capable of reducing power consumption accompanying the supply of gradation data. CONSTITUTION: The display driving circuit is provided with 1st-Mth SR blocks BLK1-BLKM which are arranged in an area on the right side with a data input control circuit 50 as a reference and hold 1st-Mth gradation data, and (M+1)th-(M+N)th SR blocks BLKM+1-BLKM+N which are arranged in the area on the left side and hold (M+1)th-(M+N)th gradation data. The 1st-(M+N)th SR blocks BLK1-BLKM+N hold the 1st-(M+N)th gradation data masking-controlled on the basis of data enable signals shifted in the respective SR blocks. The 1st-Mth gradation data are set to a mask unreleased state in the order of 1st-Mth data masking circuits 521-52M. The (M+1)th-(M+N)th gradation data are set to a mask released state in the order of (M+1)th-(M+N)th data masking circuits 52M+1-52M+N.
