Abstract
The present invention is a novel pixel structure, and method for making the same, that reduces wasteful voltage drop associated with other pixel structures that cover their pixel elements with a final passivation layer. The presently claimed pixel structure is a combination of a thin film transistor (TFT), an associated pixel element, and a passivation layer. The TFT is first deposited atop a suitable substrate and patterned. Then, the passivation layer is deposited on top of the thin film transistor. Contact cuts are made into the passivation layer where the pixel element is to contact the TFT. Finally, the pixel element is deposited--lying atop the passivation layer and contacting with the underlying TFT where the contact cuts were made in the passivation layer.
