DISPLAY DEVICE

摘要

PURPOSE: A display device is provided to use a red color filter layer as an interlayer insulating film to electrically insulate a gate electrode and source/drain electrodes, thereby removing a separate process for forming a color filter layer. CONSTITUTION: A substrate(200) comprises a red sub pixel area, a green sub pixel area, and a blue sub pixel area. A buffer layer(210) is formed on the substrate. A gate insulating film(230) is formed on the entire substrate including a poly silicon pattern. A semiconductor layer includes source/drain areas(220a,220c) and a channel area(220b). The semiconductor layer is formed on a transistor area of each sub pixel area. A first capacitor electrode(220d) is formed on a capacitor area of each sub pixel area.
