Abstract
Transflective display panel and fabrication methods thereof. A substrate with a transmissive area disposed thereon is provided. A planarization layer is deposited on the substrate and a hole is then formed in the planarization layer to expose the transmissive area. A first reflective layer and a second reflective layer are formed on the planarization layer in sequence. An etching process is then performed to pattern the first reflective layer and the second reflective layer to expose the transmissive area. The etching process has a first etching rate to the first reflective layer and a second etching rate to the second reflective layer, which is larger than the first etching rate. A transparent electrode layer is then formed on the second reflective layer and the transmissive area.
