Abstract:
In a display device, a light shield structure for reducing the transmission of incident light through a gap region located between adjacent ones of a plurality of metal pixels, said light shield structure comprised of:an antireflective coating material deposited primarily within said gap region to form a light shield such that transmission of incident light through said gap region towards underlying active devices is reduced; a composite passivation layer disposed above said plurality of metal pixels and said antireflective coating material; and a layer of liner material deposited above said plurality of metal pixels and into said gap region, wherein said antireflective coating material is deposited within said gap region with sufficient thickness to compensate for step height differences between said adjacent ones of said plurality of metal pixels and to improve adherence and integrity of said thin composite passivation layer and ease an LC alignment process.
