  • Patent number: 6421160
    Abstract: A transmissive display device using a micro light modulator that is capable of improving a light efficiency. In the display device, each of first and second transparent substrates has first and second surfaces. A plurality of stationary members are provided on the first surface of the first transparent substrate in a line with and at a desired distance from each other in a stripe shape. A plurality of movable members are opposed to portions at which the stationary members are not provided on the first transparent substrate and takes a bridge shape to have each end secured to onto the first surface of the second transparent substrate and a center portion floated by a desired distance. spacers are provided at the edges of the display device in such a manner that the first surface of the first transparent substrate is opposed to the first surface of the second transparent, thereby constantly keeping a distance between each stationary member and each movable member.

In the display device, a plurality of stationary members are provided on the first surface of the first transparent substrate in a line with and at a desired distance from each other in a stripe shape. A plurality of movable members are provided on the first transparent substrate and takes a bridge shape to be spaced from the stationary members and have each side overlapped with the stationary members. A light path controller is formed at each portion corresponding to the movable members on the second transparent substrate in such a manner to be spaced from the adjacent members, to reflect a light passing through a light path between each station member and each movable member such that the light is progressed perpendicularly to the second transparent substrate.
