Embodiment approach 1
[0047] figure 1 It is a diagram showing the configuration of a pixel circuit corresponding to one pixel of the image display device according to Embodiment 1 of the present invention. In the figure, for Figure 18 The parts corresponding to the respective parts of are given the same symbols. exist figure 1 In the illustrated pixel circuit, a variable capacitor Cc as a capacity variable mechanism and a Cc control line 20 for controlling the variable capacitor Cc are newly provided.
[0048] The variable capacitor Cc is a capacitor used to reduce the influence of the above-mentioned parasitic capacitance, and is composed of an insulating layer Z and a channel layer CN sandwiched between the first electrode M1 and the second electrode M2, and a thin film transistor. The layer structure is almost the same. The first electrode M1 is connected to the Cc control line 20 . In addition, the second electrode M2 is connected to the gate of the drive transistor Td.

Embodiment approach 2
[0138] In the above-mentioned Embodiment 1, for the respectively set figure 1 The configuration example of the Tth control line 11 and the Cc control line 20 shown in , has been described, but as long as the high potential is supplied to the variable capacitor Cc during the threshold voltage detection period and the writing period, and the low potential is supplied to the variable capacitor Cc during the light emitting period, potential, so in Embodiment 2, such as Figure 10 As shown, it may be a configuration example in which the Tth control line 11 and the Cc control line 20 are shared by the same Tth / Cc control line 30 . The potential of the Tth / Cc control line 30, and Figure 5 The potential of the Tth control line 11 (Cc control line 20 ) shown in , changes in the same way.
Embodiment approach 3
[0140] In addition, in the above-mentioned Embodiment 1, for figure 1 An example of using the variable capacitor Cc in the pixel circuit with the configuration shown above has been described, but any pixel circuit can be applied to any connection type as long as it has a driving transistor and a transistor for threshold voltage detection. In addition, it is only necessary to connect the variable capacitor Cc having the requirements described in the first embodiment to the gate of the drive transistor.
[0141] also, Figure 11 It is a diagram showing the configuration of a pixel circuit corresponding to one pixel of a current-controlled image display device. The pixel circuit shown in this figure is equipped with: threshold voltage detection transistor Tth', organic EL element OLED', drive transistor Td', switching transistor T2', auxiliary capacitor Cs', power supply line 40, image signal line 41, and Tth control / scanline 42.
