A plasma display device includes: a dielectric layer on which a plurality of through-holes of a dielectric layer is disposed in a matrix shape; upper and lower electrode layers formed at both upper and lower surfaces of the dielectric layer; upper and lower substrates disposed on the outer surface of the upper and lower electrode layers; and a third electrode layer having a plurality of third electrodes which are formed between the upper substrate and the upper electrode layer, or the lower substrate and the lower electrode layer, and are insulated from the upper and lower electrode layers. Accordingly, a plasma display device can be realized which has stability and efficiency of a micro discharge. In addition, each pixel can concurrently carry out a sustain discharge by applying an alternating voltage to upper and lower electrodes forming sustain electrodes.

When a data transferring transistor turns on, luminance data being applied to a data line is set in a drive transistor in the form of a data voltage. A current corresponding to the data voltage thus set flows to the drive transistor and simultaneously the same current flows to a first current mirror transistor. Then, a current corresponding to the ratio of a driving capability of a second current mirror transistor to that of the first current mirror transistor flows to the second current mirror transistor.

Display apparatus with function which makes gradiation control easier

When the scanning line turns high and the first transistor turns on to write luminance data, a potential corresponding to the luminance data in the organic light emitting diode is set in both the gate electrode of the second transistor. At the same time, the fourth transistor turns on, and the electric charge in the anode of the organic light emitting diode is pulled out to ground potential by way of the fourth transistor. Also, at the same time, the third transistor turns off, so that any shoot-through current from the power supply line Vdd will be prevented. Thus the potential at the anode of the organic light emitting diode becomes the same as the ground potential. Thus, the luminance data already present in the optical element is initialized.
