Abstract: At a wire crossover portion, extension wires, which are electrically connected to scanning electrode connecting wires, extend so as to cross over the other scanning electrode circuitous wires without having contact with the other scanning electrode circuitous wires and to be electrically connected to the corresponding scanning electrode circuitous wire.

Abstract: To suppress light loss without deteriorating resolution of a projected image, light is first polarized and separated by a polarizing beam splitter. Green light is separated from a light flux emitted by the polarizing beam splitter by a dichroic mirror having a green light reflection property. A light flux containing blue and red light, which is transmitted by the dichroic mirror, is separated into red light and blue light by a dichroic prism. Resultant color light is modulated and reflected by reflection light valves, returned to the corresponding dichroic mirror or dichroic prism, and combined by the dichroic mirror and the dichroic prism. Resultant combined color light is projected via the polarizing beam splitter and a projection lens. The dichroic prism transmits s-polarized light having wavelengths less than a wavelength substantially within a wavelength band of green light and reflects s-polarized light having larger wavelengths.

Abstract: There is disclosed a display device using a color wheel having a color filter Cw, in addition to normal color filters corresponding to the three primary colors. The filter Cw has almost flat spectral transmission characteristics. Brightness information included in a color image signal is quantized with (n+m) bits.

Only brightness information to which the human eye is visually sensitive is reproduced by the filter Cw having a lower transmissivity. This can eliminate a lack of the number of gray levels due to a constraint on the minimum switching speed of a light valve. Furthermore, the brightness little deteriorates.
