Abstract:
1. An active-matrix display device comprising: a display section including a matrix of pixel circuits to which image information is given in the form of current, a plurality of scanning lines for selecting each pixel circuit, and a plurality of data lines for supplying each pixel circuit with the image information; and a driving circuit which holds the image information, and then writes the image information onto each pixel circuit by feeding the image information in the form of current to each of the plurality of data lines, wherein the current flowing through each of the plurality of data lines coincides with a writing current independently of variations in the driving circuit, and wherein the plurality of data lines write a plurality of pieces of image information data on a row of data line drivers in a time sharing manner by arranging an impedance transforming transistor, which operates in a saturation region thereof when the image information is written, between a converting unit and a current source for supplying the driving circuit with the image information, wherein the converting unit converts the image information supplied in the form of current into a voltage.
