ELECTROLUMINESCENT DISPLAY DEVICE

摘要

In an active matrix electroluminescent display device having an array of pixels, a drive transistor and an electroluminescent display element in each pixel are connected in series between a power line for supplying or drawing a controllable current to or from the display element and a common potential line. The power line and the common potential line each comprise a sheet electrode shared among all pixels of the array. In this arrangement, sheet electrodes are used both for the current supply to the EL display element and the current sink. This reduces considerably the line resistance.
