ABSTRACT:
In order to solve a subject that a polycrystalline silicon TFT liquid crystal display apparatus of the driving circuit integration type cannot adopt a technique for reducing the power consumption by an output section, according to the present invention, for example, a sampling latch circuit which composes a horizontal driving circuit (data line driving circuit) of an active matrix type display apparatus is configured such that, when a 1-bit mode (2-gradation mode) is set, a control signal A of the “H” level and another control signal B of the “L” level (low level) are outputted from a 1-bit mode control circuit (16) to place only AND circuits (31-2and32-2) corresponding to the most significant bit (MSB) into a passage permitting state to place only latch circuits (35-2and36-2) of the MSB into a data writing permitting state (active state) while the remaining latch circuits (35-0, 35-1, 36-0and36-1) are placed into a data writing inhibiting state (inactive state).
