DISPLAY DEVICE AND MANUFACTURING METHOD OF DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a pixel in which the normal display of an image (video) is possible even if a sustain period is shorter than an address period in a drive method combining digital gray scales and time gray scales, and in which operation can be compensated by changing the electric potential of a signal line even if an EL driver transistor is brought into a normally-on state due to deterioration.SOLUTION: One of a source region and a drain region of an erasure TFT 105 is connected to an electric current supply line 108, and the other is connected to a gate signal line 106. It is possible to change a voltage between a gate and a source of an EL driver TFT 102 by changing the electric potential of the gate signal line 106 to reliably render the EL driver TFT 102 into a non-conducting state even if the EL driver TFT 102 is brought into the normally-on state due to a shift in the threshold of the EL driver TFT 102.
