In a heat generation unit of the present invention, a holder having an elastic force tube used for holding a film-sheet-shaped heat generation element that generates heat upon application of a voltage thereto is disposed in a container together with the heat generation element. The heat generation element is held in a predetermined position in the container by the elastic force of the holder, with electric power being supplied from power supply members thereto through the holder, so that the heat generation element can be reliably held in the container, with a partial heat generation in the holder of the heat generation element being suppressed.

The present invention relates to a method of driving an active-matrix type of liquid crystal display device that has a plurality of row electrodes to which a scanning signal is applied, a plurality of column electrodes to which a data signal is applied, and a plurality of picture elements (pixels) formed at a plurality of intersections between these row and column electrodes, each of these pixels comprising a liquid crystal layer and a two-terminal element having non-linear resistance characteristics connected in series therewith by means of applying a voltage of a difference signal between a scanning signal and a data signal to the pixels. A compensatory voltage is applied to each pixel immediately before a data write period during which the liquid crystal layer of the pixel is charged with a data charge voltage corresponding to a display gradation. This compensatory voltage is a voltage that charges the liquid crystal layer with a compensatory charge voltage of a polarity opposite to that of the data charge voltage. The relationship between the two voltages is such that when the magnitude of the data charge voltage is large, that of the compensatory charge voltage is small; when the magnitude of the data charge voltage is small, that of the compensatory charge voltage is large. This reduces the occurrence of afterimages that are caused by I-V characteristic shift in a non-linear two-terminal element.

In a method for driving an active matrix type liquid crystal display device having a liquid crystal panel having the structure that a set of liquid crystal layers and two-terminal active layers are connected in series between a set of column electrodes and a set of row electrodes, a display operation being carried out by applying a difference signal between each column electrode and each row electrode, the difference signal is set so as to have a voltage having an inverse characteristic to the I-V characteristic of the two-terminal active element and is applied between the column and row electrodes to thereby depress occurrence of flicker. In addition, within a period except for a selection period for which an actual display operation is carried out in the liquid crystal panel, the difference signal having amplitude voltage equal to or above the maximum amplitude voltage set for the display operation is applied between the column and row electrode sets for a predetermined period to thereby prevent degradation of display quality due to the shift characteristic of the two-terminal active element which has been driven, and due to the asymmetry of the voltage-current characteristic of the two-terminal active element between the positive and negative polarity regions thereof.
