<p>A method of fabricating a liquid crystal display panel, comprising the following steps: step 1, providing a substrate (20); step 2, forming a black photoresist material layer on the substrate (20), forming a preset pattern through a photomask process, and further forming a black matrix (22); step 3, forming an isolation layer (30) on the black photoresist material layer; Step4, forming a first metal layer on the isolation layer (30), forming a second metal layer on the first metal layer, forming a preset pattern through a photomask process, and further forming a source/drain region (42) and a storage capacitor Com electrode (44); step 5, forming an ohmic contact layer on the second metal layer, forming a preset pattern through a photomask process, and further forming a phosphorus doped film (52) on a metal electrode; step 6, forming a channel layer on the ohmic contact layer, forming a preset pattern through a photomask process, and further forming an island (62); step 7, forming a gate insulating layer (70) on the channel layer, forming a third metal layer on the gate insulating layer (70), forming a preset pattern through a photomask process, further forming a gate and a storage capacitor counter electrode, and arranging the storage capacitor at the edge position of the black matrix (22); step 8, forming a protective layer (90) on the third metal layer; step 9, forming R, G and B pixels (102, 104, 106) on the protective layer (90); step 10, forming via holes at positions corresponding to the source electrode and storage capacitor on the R, G and B pixels (102, 104, 106); step 11, forming a transparent conductive layer on the R, G and B pixels (102, 104, 106), forming a preset pattern through a photomask process, and further forming pixel electrodes, and thus forming a COA substrate; step 12, attaching the COA substrate (200) on an upper substrate (400), injecting liquid crystal between the COA substrate (200) and the upper substrate (400), and thus forming the liquid crystal display panel.</p> |
