Abstract: If the threshold of a thin film transistor is depleted, a leak-induced voltage drop takes place and the desired voltage cannot be obtained. Depending on the severity of the phenomenon, the thin film transistor may fail to function. This disclosure offers a thin film transistor circuit having a first transistor connected to a low voltage, and a second transistor connected to the gate of the first transistor. When the gate voltage of the second transistor is changed from the high level to the low level, the gate voltage of the first transistor is brought to a voltage level lower than the low voltage.

Abstract: A liquid crystal material is driven in a twisted nematic mode so that while liquid crystal molecules lose, on a stripe electrode, rotary power toward a direction along an electric field by a voltage applied between the stripe electrode and a second electrode and form, in a region between the adjacent stripe electrodes, refractive index distribution of a lenticular lens that includes a cylindrical lens in which a cylindrical axis is arranged in a first direction. The cylindrical lens faces at least two rows of pixels, and has an effective refractive index for causing light from the at least two rows of pixels to advance in separating directions from each other after emission from a second polarizing plate. A distance d of a cell gap and an interval s between the adjacent stripe electrodes satisfy the relation of 3.5≦s/d≦7.
