摘要： A first pixel circuit and a second pixel circuit are connected to a first data signal line. A third pixel circuit and a fourth pixel circuit are connected to a second data signal line. The first data signal line is connected to a first connection wire provided to a frame region. The second data signal line is connected to a second connection wire provided to the frame region. A sum of resistance values of the first data signal line and the first connection wire is smaller than a sum of resistance values of the second data signal line and the second connection wire.

摘要： A drain electrode 25 of a TFT 21 overlaps with a gate electrode formed integrally with a gate line 23. A pixel electrode 22 has a main body part formed on a first side of the gate line 23, and an extension part extending in an extending direction of a data line 24 and covering an overlapping portion of the gate electrode and the drain electrode 25. The drain electrode 25 is not formed on a second side of the gate line 23, whereas the extension part of the pixel electrode 22 is formed also on the second side of the gate line 23. Even when a position of the pixel electrode 22 is shifted in the extending direction of the data line 24, a parasitic capacitance between a drain and a source of the TFT 21 is kept constant, because an area of a portion where the extension part of the pixel electrode 22 overlaps with the gate line 23 does not change. With this, degradation of display quality due to a variation in the parasitic capacitance between the gate and drain of the TFT 21 can be prevented.

摘要： Provided is a display device with pixel circuits, each including first compensation transistor connected to a control terminal of a drive transistor at one conductive terminal, an intermediate node at another conductive terminal, and a scanning line at a control terminal, a second compensation transistor connected to the intermediate node at one conductive terminal, a conductive terminal of the drive transistor at another conductive terminal, and the scanning line at a control terminal, and a capacitor connected to the intermediate node at one electrode and a control line at another electrode. The driver circuit changes a potential of the scanning line from on to off level and also changes a potential of the control line from a second level to a first level, in an opposite direction to the change in the potential thereof.

摘要： From a back side of an insulating substrate 90, a laser beam is applied to a spot where an initialization line Vini is superimposed on the semiconductor layer SI that serves as a first conductive terminal of a second initialization transistor T7 while sandwiching an insulating film therebetween. Thus, a gate insulating film 91 and a first interlayer insulating film 92, which are sandwiched between the semiconductor layer SI and the initialization line Vini, disappear by evaporation, and a laser irradiation area LA of the semiconductor layer SI is connected to the initialization line Vini, by which a connection portion CP is formed. As a result, a voltage to be applied to the organic EL element OLED becomes equal to or less than a threshold voltage. Therefore, the organic EL element OLED is constantly in a lighting-off state, and the pixel circuit 11 is constantly kept black.
