Liquid crystal display device with potential varying capacitance electrode
Abstract:
In a liquid crystal display device in which one pixel is divided into the plurality of subpixels, a narrow picture-frame is realized by decreasing a wiring region without reducing a display quality. One of two sub-pixel portions includes a second transistor (TB) having a gate connected to a first scanning signal line (GL) and having a source connected to a data signal line (SL), a pixel electrode (EB) connected to a drain of the second transistor (TB), a liquid crystal capacitance (ClcB) formed by a common electrode (41) and the pixel electrode (EB), a third transistor (TC) having a gate connected to a second scanning signal line (G2L) and having a source connected to a line SEL, a capacitance electrode (EC) connected to a drain of the third transistor (TC), and a capacitance (Cl) formed by the pixel electrode (EB) and the capacitance electrode (EC). A high potential and a low potential are alternately provided to the line SEL for each one frame. The second scanning signal line (G2L) is selected after the first scanning signal line (GL) is selected.
Abstract(Chinese):

在一个像素被划分成多个子像素的液晶显示装置中，通过减少布线区域而不降低显示质量来实现窄的图像帧。 两个子像素部分中的一个包括具有连接到第一扫描信号线（GL）并且具有连接到数据信号线（SL）的源极的栅极的第二晶体管（TB），连接到数据信号线 第二晶体管（TB）的漏极，由公共电极（41）和像素电极（EB）形成的液晶电容（ClcB），具有与第二扫描信号线（G2L）连接的栅极的第三晶体管 ），并且具有连接到线SEL的源极，连接到第三晶体管（TC）的漏极的电容电极（EC）和由像素电极（EB）和电容电极（EC）形成的电容（Cl） 。 每一帧交替地向线SEL提供高电位和低电位。 在选择第一扫描信号线（GL）之后，选择第二扫描信号线（G2L）。
