Patent ID: 7019807

Claim:
An electro-optic device, comprising: a substrate; data lines disposed on the substrate and extending in a set direction; scanning lines disposed on the substrate and extending in a direction perpendicular to the data lines; and pixel electrodes and thin film transistors disposed on the substrate and each being arranged so as to correspond to the regions of intersection between the data lines and the scanning lines; a storage capacitance having pixel-potential capacitive electrodes coupled to the pixel electrodes and thin film transistors; fixed-potential capacitive electrodes facing the pixel-potential capacitive electrodes; a dielectric film arranged between the pixel-potential capacitive electrodes and the fixed-potential capacitive electrodes; a first interlayer insulator arranged between the fixed-potential capacitive electrodes and the scanning lines; a second interlayer insulator arranged between the data lines and the fixed-potential capacitive electrodes; a shield layer having a fixed potential and being arranged between the pixel electrodes and the data lines; and a third interlayer insulator arranged between the pixel electrodes and the data lines, the third interlayer insulator including: a fourth interlayer insulator arranged between the pixel electrodes and the shield layer; a fifth interlayer insulator arranged between the shield layer and the data lines, at least one of the fourth interlayer insulator and the fifth interlayer insulator having a relative dielectric constant lower than that of the dielectric film, the fifth interlayer insulator having a relative dielectric constant lower than that of the fourth interlayer insulator; and at least one of the first interlayer insulator, the second interlayer insulator, and the third interlayer insulator having a relative dielectric constant lower than that of the dielectric film constituting the storage capacitance.
