Abstract
There is disclosed an active matrix reflective liquid crystal display panel on which an active matrix circuit is integrated with peripheral driver circuits. Metal lines in the peripheral driver circuits are formed simultaneously with pixel electrodes. Thus, neither the process sequence nor the structure is complicated.
