摘要： In this invention, as a basic structure, an impedance element is connected in series to a liquid crystal layer (liquid crystal capacitance) of each pixel. The impedance of the impedance element is varied in accordance with a display signal. The resistance values of variable resistance elements are varied in accordance with a display signal being held by a display signal holding means that is provided in each pixel, whereby the impedance of the impedance element varies in accordance with the resistance states of the variable resistance elements. If an AC voltage is applied across the basic structure, an AC voltage produced by voltage division in accordance with the impedance of the impedance element is applied to the liquid crystal layer. Therefore, the AC voltage applied to the liquid crystal layer and hence the gradation level of the liquid crystal layer can be controlled by adjusting the impedance of the impedance element in accordance with a display signal. A display signal is not input to the liquid crystal layer directly and consumed there. Instead, an AC voltage produced by dividing, by the impedance element and the liquid crystal layer, an AC voltage corresponding to a display signal that is temporarily held by the holding means such as a capacitor is applied to the liquid crystal layer. Therefore, the power consumption can be reduced.

摘要翻译： 在本发明中，作为基本结构，阻抗元件与各像素的液晶层（液晶电容）串联连接。 阻抗元件的阻抗根据显示信号而变化。 可变电阻元件的电阻值根据由设置在每个像素中的显示信号保持装置保持的显示信号而变化，由此阻抗元件的阻抗根据可变电阻元件的电阻状态而变化。 如果在基本结构上施加交流电压，则将根据阻抗元件的阻抗的分压产生的交流电压施加到液晶层。 因此，可以通过根据显示信号调整阻抗元件的阻抗来控制施加到液晶层的AC电压以及因此液晶层的灰度级。 显示信号不直接输入到液晶层并在那里消耗。 相反，通过将阻抗元件和液晶层除以对应于由诸如电容器的保持装置暂时保持的显示信号的AC电压而产生的AC电压被施加到液晶层。 因此，可以降低功耗。

摘要： Some conventional liquid crystal display devices were hard to make connection to a pixel electrode interposed between liquid crystal layers when a picture element is configured by laminating a plurality of liquid crystal layers. The liquid crystal display device comprises a first substrate having a first applying means for applying a first signal; a first electrode opposed to the first substrate; at least one liquid crystal layer interposed between the first substrate and the first electrode; a pillar made of an insulating material, formed on the first substrate so as to have a lateral face and to pierce through the liquid crystal layers; and at least one first wiring pattern formed on the lateral face of the pillar to connect the first applying means and the first electrode. Specifically, this liquid crystal display device has the pillar and the wiring pattern formed on the lateral face of the pillar as the inter-connector to connect to the pixel electrode interposed between the liquid crystal layers. The pillar may be formed into, for example, a truncated pyramid shape, and its top face can be used to connect the pixel electrode with the wiring pattern.

摘要： A liquid crystal display device having a liquid crystal layer driven by a data signal which comprises a TFT for selecting the data signal; and a ferroelectric layer of which a polarized state is controlled corresponding to the data signal selected by the TFT, and the liquid crystal layer responds to the polarized state of the ferroelectric layer, and the liquid crystal layer is driven when the liquid crystal layer responds to the polarized state of the ferroelectric layer. Since the ferroelectric layer can keep stable the polarized state for a long duration, a driving frequency can be reduced substantially to a substantially DC level, and power consumption is reduced to a great extent. In addition, the ferroelectric layer formed in a pixel divides the liquid crystal corresponding to the polarized domains of the ferroelectric layer, thereby showing an analogous grayscale image.
