Patent ID: 7002647

Claim:
A display device, comprising: a panel structure having a first substrate and a second substrate bonded to each other with a predetermined gap separating them and an electrooptic substance held in the gap between the first substrate and the second substrate; a set of thin film transistors, a planarizing film covering said thin film transistors, and a set of pixel electrodes arranged on the planarizing film being formed on the first substrate; an opposite electrode being formed vis-a-vis the set of pixel electrodes on the second substrate; and the planarizing film of the display device being made of a photosensitive material and formed to have a varying thickness in the first substrate by means of an exposure process, wherein said first substrate has thereon a pixel array section formed by the pixel electrodes and thin film transistors for driving the pixel electrodes and a drive circuit section formed by thin film transistors for driving the pixel array section, and said planarizing film is formed so as to extend from the pixel array section to the peripheral drive circuit section and to have a thickness differentiated between the pixel array section and the drive circuit section.
