Electro-optical device and electronic apparatus including the same

Abstract

The present invention provides an electro-optical device such as a liquid crystal device etc, wherein the signals in the controlling scanning direction are stably supplied to the scan line driver circuit to prevent the miss work of the scan line driver circuit. The electro-optical device is provided, on the substrate, with: a plurality of pixel portions, a plurality of scanning lines and a plurality of data lines disposed in the pixel area, for supplying the scanning signals to the scanning line drive circuit driving the plurality of scanning lines. The electro-optical device is further provided with a forward-direction control signal for controlling the scanning line drive circuit to supply the scanning signals to the plurality of scanning lines in a first order, a reverse-direction control signal for controlling the scanning line drive circuit to supply the scanning signals to the plurality of scanning lines in a second order, which is the reverse of the first order; wherein the forward-direction control signal and the reverse-direction control signal are supplied to a reverse-direction control signal generating circuit of the scanning line drive circuit.

Description

technical field [0001] The present invention relates to the technical field of electro-optical devices such as liquid crystal devices, and electronic equipment including such electro-optical devices, such as liquid crystal projectors. Background technique [0002] When such an electro-optic device is installed in, for example, a liquid crystal projector, etc., depending on the positional relationship of the optical system, it may be required to form, for example, an upside-down image, an upside-down, left-right, or inside-out image. For example, in a multi-panel color projector that uses a liquid crystal device as a light valve to combine three pieces, the white light is emitted from the light source until it is temporarily separated by color through a half-mirror, reflector, prism, etc. and then is used by each color. Between the modulation of the light valve and subsequent recombination into one kind of light, there are light of an even-numbered color reflected by the half...

Problems solved by technology

Furthermore, because the wiring path for supplying the control signal from, for example, the external circuit connection terminal to the scanning line driving circuit is very long, there is a possibility that the control signal is affected by noise from other circuits, and there is also a possibility that the control signal may be affected by noise in the standard direction. There may be technical problems such as phase, amplitude, and waveform deviations between the control signal and the control signal in the opposite direction.
