Abstract
A reflective type active matrix display panel having pixel electrodes formed on a substrate is manufactured as follows: an insulating film is formed all over the substrate including the pixel electrodes; the surface of the insulating film is planarized by use of a polishing material including an etchant for etching the insulating film; and a reflective layer and a liquid crystal layer are formed on the planarized insulating film. The surfaces of the pixel electrodes are also planarized to have only the liquid crystal layer formed on the planarized pixel electrodes. The display panel has pixel transistors arranged into a matrix pattern on the substrate. Connected to the transistors are pixel electrodes and wirings arranged into a matrix pattern Signals are applied to the pixel electrodes via the wirings. The transistors, pixel electrodes, and wirings are provided in a display pixel area on the substrate. The display panel also has drive circuits for scanning the signals, formed around the display pixel area.
