Abstract
A reflection type semiconductor display device which can make satisfactory display even when external light is not satisfactorily intense is provided. A reflection type semiconductor display device according to the present invention can take in light other than incident light on a liquid crystal panel to be an auxiliary light source using optical fibers, and thus, display of high quality level can be made even indoors or in a place where light is faint. Further, by combining the semiconductor display device with a front light, insufficient amount of light can be supplemented with the front light.
Claims58
A reflection type semiconductor display device in which light emitted from one end of an optical fiber enters said reflection type semiconductor display device, wherein the light is external light taken in from the other end of the optical fiber.
A reflection type semiconductor display device in which light emitted from one end of an optical fiber enters a counter substrate of said reflection type semiconductor display device, wherein the light is external light taken in from the other end of the optical fiber.
A reflection type semiconductor display device in which light emitted from one end of an optical fiber enters a light guide plate provided so as to oppose to said reflection type semiconductor display device, wherein the light is external light taken in from the other end of the optical fiber.
A reflection type display device comprising:
- a first substrate;
- a plurality of reflective pixel electrodes over said first substrate;
- a second substrate provided so as to oppose to said first substrate;
- a liquid crystal provided between said first substrate and said second substrate;
- a light guide plate over said second substrate;
- and
- an optical fiber having first and second ends,
- wherein said first end is operationally connected to an edge of said light guide plate and said second end is disposed so that external light can enter said second end.
