An active matrix type display apparatus of the present invention includes
pixel circuits each having an electrooptic device that changes brightness
thereof according to a current flowing therein and driving said
electrooptic device on the basis of brightness data supplied via a data
line, and a current type pixel driving circuit for supplying each of said
pixel circuits with a writing current that temporally increases in
magnitude of a current value thereof within a cycle of writing of said
brightness data. In the matrix type display apparatus of the present
invention, the magnitude of the current value of the writing current is
temporally increased within the writing cycle, whereby the writing
current is limited to a low level (or zero) in an early stage of the
writing cycle. Thus, the average value of the writing current is reduced.
