LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

THEREIS PROVIDED A LIGHT EMITTING DEVICE IN WHICH LOW POWER CONSUMPTION CAN BE REALIZED EVEN IN THE CASE OF A LARGE SCREEN. THE SURFACE OF A SOURCE SIGNAL LINE OR A POWER SUPPLY LINE IN A PIXEL PORTION IS PLATED TO REDUCE A RESISTANCE OF A WIRING. THE SOURCE SIGNAL LINE IN THE PIXEL PORTION IN MANUFACTURED BY A STEP DIFFERENT FROM A SOURCE SIGNAL LINE IN A DRIVER CIRCUIT PORTION. THE POWER SUPPLY LINE THE PIXEL PORTION IS MANUFACTURED BY A STEP DIFFERENT FROM A POWER SUPPLY LINE BED ON A SUBSTRATE. A TERMINAL IS SIMILARLY PLATED TO MADE THE RESISTANCE REDUCTION. IT IS DESIRABLE THAT A WIRING BEFORE PLATING IS MADE OF THE SAME MATERIAL AS A GATE ELECTRODE AND THE SURFACE OF WIRING IS PLATED TO FORM THE SOURCE SIGNAL LINE OR THE POWER SUPPLY LINE.
