Abstract:
A projector comprising:a first polarizing plate for subjecting light emitted from a light source to predetermined polarization and then transmitting the polarized light;a liquid crystal display for receiving and reflecting the light transmitted through the first polarizing plate in an oblique direction; anda second polarizing plate for transmitting the reflected light emitted from the liquid crystal display in a direction orthogonal to the first polarizing plate,the light transmitted through the second polarizing plate being projected onto a screen,the liquid crystal display including:a plurality of pixel electrodes provided in a matrix on a first substrate;a thin film transistor formed on the first substrate to be connected with the corresponding pixel electrodes; anda liquid crystal layer interposed between the pixel electrodes provided on the first substrate and a common electrode on a second substrate opposed to the first substrate, the liquid crystal layer being driven by each pixel electrode to perform display operation,wherein the thin film transistor utilizes a poly silicon layer for an active layer,an initial direction of each liquid crystal molecule of the liquid crystal layer interposed between the first and second substrates is controlled in a nearly vertical direction with respect to the pixel electrode,a liquid crystal molecule with a molecular structure having a fluorine side chain is selected as a liquid crystal material to be used for the liquid crystal layer, andthe pixel electrode is formed of a reflection material and utilized as a reflection layer.
