摘要： An image display device includes pixel circuits, a power supply line, and a data line for supplying a data signal to the pixel circuits. The pixel circuits each include a light emitting element, a drive transistor for controlling light emission of the light emitting element, a storage capacitor provided between the data line and a gate electrode of the drive transistor, a both-end connection switch for connecting both ends of the storage capacitor to each other, and a current interruption switch for interrupting a path of a current flowing from the power supply line through the both-end connection switch. Before the data signal is supplied to each of the pixel circuits, the both-end connection switch connects the both ends of the storage capacitor to each other, and the current interruption switch is disconnected.

摘要： The present invention realizes a high-quality display by optimizing a light emitting efficiency among pixels which differ in light emitting characteristic from each other by enabling to apply voltages corresponding to pixels which differ in color from each other while suppressing brightness irregularities attributed to a voltage drop of a power source line. Only power source lines Lv of sub pixels B and a bypass line Lb are connected with each other in a first row (X1), only power source lines Lv of sub pixels R and a bypass line Lb are connected with each other in a second row (X2), and only power source lines Lv of sub pixels G and a bypass line Lb are connected with each other in a third row (X3). Then, these arrangements of the sub pixels B, R, G, the power source lines Lv and the bypass lines Lb are repeated.

摘要： An inexpensive organic electroluminescent display device is realized by using a data driver IC for liquid crystal that is used in a liquid crystal display device, as a driver of the organic electroluminescent display device. In an active-matrix organic electroluminescent display device that has a pixel circuit capable of controlling light emitting luminance per time in accordance with magnitude of a grey scale voltage, a control signal is supplied from a timing control IC to the data driver so that the polarity is reversed twice consecutively, or a control signal is supplied from the timing control IC to the data driver so that a mode of not reversing the polarity is selected. This control signal need not necessarily be provided in the timing control IC and may be formed in a circuit on a substrate that is not an IC.
