摘要： The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced.

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.
