    摘要: A liquid crystal display device is provided which is capable of sufficiently decreasing power consumption in permanent display of still images while keeping high quality display in transparent mode, in high resolution display panels. In each pixel circuit, a pixel electrode is connected to a source line via a third transistor. When a refreshing circuit performs a refreshing operation, a boosting signal line is supplied with a voltage pulse. If the pixel electrode is at a high voltage level at this time point, a voltage at a node is boosted and a first transistor turns ON to supply a reference voltage to the pixel electrode as a refreshing voltage. If the pixel electrode is at a low voltage level, there is no boost, and the first transistor stays in OFF state, so a node assumes a voltage which is given by an off-resistance ratio of the first and the third transistors, and this voltage is supplied to the pixel electrode.

    摘要: A liquid crystal display device includes a data signal line driving circuit which separately drives data signal lines of an active matrix pixel array.

    摘要: A display device which can prevent deterioration of a liquid crystal and reduction in display quality at low power consumption without lowering an aperture ratio is provided. An opposite voltage (Vcom) is applied to an opposite electrode (80) of a liquid crystal capacitive element (Clc). One ends of a pixel electrode (20), a first switch circuit (22), a second switch circuit (23), and a first terminal of a second transistor (T2) form an internal node (N1). The other ends of the first switch circuit (22) and the second switch circuit (23) are connected to a source line (SL) and a voltage supply line (VSL), respectively. A control terminal of a first transistor (T1) in the second switch circuit (23), a second terminal of the second transistor (T2), and one end of a boost capacitive element (Cbst) form an output node (N2). The other end of the boost capacitive element (Cbst) and the control terminal of the second transistor (T2) are connected to a boost line (BST) and a reference line (REF), respectively. This configuration makes it possible to perform an action (self-refresh action) to return the absolute value of the voltage between both ends of a display element part to the value at the time of a last writing action without performing a writing action.
