Abstract
The object of this invention is to enhance the display quality of reflection type liquid crystal display device having the constitutions of an organic insulating film is formed on a thin film transistor formed on a substrate, and contact holes and bumps are formed at the positions for forming reflection electrodes on the organic insulating film. The reflection electrodes are formed thereon, and drain electrodes and reflection electrodes 38 are connected through the contact holes. The effect of this invention is since the bumps are formed only in the portions of the reflection electrodes, patterning of the reflection electrodes is easy, and insulation failure between source bus wirings and reflection electrodes does not occur, and the display quality is enhanced.
