Abstract:
An active-matrix type liquid crystal display comprising:a plurality of pixel electrodes provided in a matrix on a first substrate; a thin film transistor formed on the substrate to be connected with the corresponding pixel electrodes; and a 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 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, an electrode absent portion for controlling the alignment of the liquid crystal is provided as an alignment control window in a predetermined region of the common electrode provided on the second substrate which is opposed to the pixel electrode, and a plurality of alignment regions having different tilt azimuths are formed in each pixel electrode region while varying the vertical alignment of the liquid crystal molecule, and 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, the pixel electrode is formed of a reflection material and is used as a reflection layer, and the liquid crystal molecule includes at least type of liquid crystal molecule from among the group indicated by the following formulas (1) to (6):
