Liquid crystal display element, liquid crystal display device, and display method employed in liquid crystal display element

摘要

Picture element electrodes (30) and common electrodes (36) are provided in one of two substrates facing each other. Each picture element (20) has a plurality of sub picture elements (22). In a range in which a signal voltage of an image signal is low, a display is carried out only in a first sub picture element (22a) having narrower electrode spacing, whereas in a range in which the signal voltage of the image signal is high, a display is carried out in both of the first sub picture element (22a) and a second sub picture element (22b) having wider electrode spacing.

1. A liquid crystal display element, comprising:
two substrates facing each other and a liquid crystal layer sandwiched between the two substrates, picture elements being provided in a matrix manner, picture element electrodes and common electrodes being provided on one of the two substrates, and each of the picture elements being divided into a plurality of sub picture elements, each of the plurality of sub picture elements having different electrode spacing between a corresponding one of the picture element electrodes and a corresponding one of the common electrodes, in a first range in which a signal voltage of an image signal is low, a display being mainly carried out in a sub picture element of the plurality of sub picture elements which has narrower electrode spacing, and in a second range in which the signal voltage of the image signal is high, a display being carried out in the sub picture element which has the narrower electrode spacing and in a sub picture element of the plurality of sub picture elements which has wider electrode spacing, wherein: each of the picture elements includes a sub picture element control section for controlling a supply of the signal voltage of the image signal to the sub picture element which has the wider electrode spacing; the sub picture element control section supplies the signal voltage of the image signal to the sub picture element which has the wider electrode spacing, in a case where the signal voltage of the image signal is not less than a threshold voltage which is a voltage corresponding to a boundary between the first range and the second range, and the sub picture element control section does not supply the signal voltage of the image signal to the sub picture element which has the wider electrode spacing, in a case where the signal voltage of the image signal is less than the threshold voltage.
