Abstract:
1. An organic light-emitting device, comprising: a substrate having a pixel area and a peripheral circuit area; a reflective layer on said substrate, said reflective layer having a first reflective part in said pixel area and a second reflective part in said peripheral circuit area; a first electrode layer having a first part on said first reflective part; a pixel definition layer on said substrate, said pixel definition layer defining a plurality of pixel openings to expose a portion of said first part of said first electrode layer, and at least one electrode contact hole to expose a portion of said second reflective part; an organic light-emitting layer on said first part of said first electrode layer; a second electrode layer having a first portion located in said pixel area and on said organic light-emitting layer, said second electrode layer having a second portion located in said peripheral circuit area and on said second reflective part, physically and electrically connecting said exposed portion of said second reflective part; a transistor on said substrate in said pixel area, wherein said transistor comprises a device electrode layer electrically coupling with said first electrode layer; and a signal electrode layer in said peripheral circuit area, wherein said signal electrode layer and said device electrode layer are formed by a same conductive layer, and said second reflective part electrically couples with said signal electrode layer.
