<P>PROBLEM TO BE SOLVED: To provide a display device with which a uniform current source can be obtained without the variations in the current value of an output stage even in a sampling period of another circuit and a high grade image free from luminance unevenness can be displayed toward a scan completion section. <P>SOLUTION: The display device operates sample-hold circuits 1031-1 to 1031-n sequentially from a first column side and final column side of a column direction to hold the samples of the video signals point-sequentially in all the sample-hold circuits and passes the first signal current I1 supplied in a first supply line ILS 101 at this point in time through TFTs 123 (-1 to -n) of the sample-hold circuits 1031-1 on the first column side to hold the samples point sequentially. The display device is provided with a horizontal selector (103) to hold the samples point sequentially by passing the second signal current I2 supplied in the second supply line ISL 102 from the sample-hold circuits 1031-n on the last column side through the TFTs 124 (-n to -1). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
