Abstract
In a display device including a pixel circuit having a transistor with a low electron mobility, low power consumption is realized without decreasing an aperture ratio. An liquid crystal capacitor element (Clc) is formed between a pixel circuit () and a counter electrode (). One ends of the pixel electrode (), a first switch circuit (), and a second switch circuit () and a first terminal of a second transistor (T) form an internal node (N). The other end of the first switch circuit () is connected to a source line (SL). The second switch circuit () has the other end connected to a voltage supply line (VSL), and is a series circuit of transistors (Tand T). A control terminal of the transistor (T), a second terminal of the transistor (T), and one end of the boost capacitor element (Cbst) form an output node (N). The other end of the boost capacitor element (Cbst) and the control terminal of the transistor (T) are connected to a selecting line (SEL) and a reference line REF, respectively. A control terminal of the transistor (T) is connected to the selecting line (SEL) through a delay circuit ().
