发明名称 PIXEL CIRCUIT AND DISPLAY DEVICE
摘要 <p>A display device that realizes a reduction in power consumption without causing deterioration of an aperture is provided. A liquid crystal capacitor element (Clc) is formed by being interposed between a pixel electrode (20) and a counter electrode (80). A counter voltage (Vcom) is applied to the counter electrode (80). One terminals of the pixel electrode (20), a first switch circuit (22), and a second switch circuit (23), and a first terminal of a second transistor (T2) form an internal node (N1). The fist switch circuit (22) and the second switch circuit (23) have other terminals connected to a source line (SL). The second switch circuit (23) is configured by a series circuit of transistors (T1 and T3), and a control terminal of the transistor (T1), a second terminal of the transistor (T2), and one terminal of a boost capacitor element (Cbst) form an output node (N2). The other terminal of the boost capacitor element (Csbt) is connected to a boost line (BST), the control terminal of the transistor (T2) is connected to a reference line (REF), and the control terminal of the transistor (T3) is connected to a selecting line (SEL).</p>
