Active organic electroluminescence panel display with blank layer covering contact opening
An active organic electroluminescence panel display and a fabricating method thereof are disclosed. A thin film transistor array comprising a plurality of thin film transistors, a plurality of datalines and a plurality of scanlines are formed on a substrate. A passivation layer is formed on the substrate, covering the thin film transistor array. A contact opening is formed in the passivation layer for exposing a prescribed area of the array. An anode layer is formed on the passivation layer and fills into the contact opening. A blank layer is formed on the anode, covering the contact opening. A shadow mask is disposed on the blank layer. Then, a sputtering process is performed to form an organic luminescent layer. The shadow mask is then removed, and a cathode layer is formed on the organic luminescent layer for forming an active organic electroluminescence panel display.
