Abstract
On a liquid crystal device substrate 1, a capacitor 85 is provided between reset signal lines 81 and 82 for applying reset potentials to the respective data lines prior to the supply of the image signals to the data lines, and a potentiostatic line 84. The capacitor 85 is formed by making use of each of the processes for producing a TFT 50 for applying the reset potentials to the respective data lines prior to the supply of the image signals to the data lines. A liquid crystal device and a projection display device employing the liquid crystal device prevent signals from circulating from data lines via a reset signal line, thus permitting higher quality of display to be achieved.
