The present invention relates to an image display device and a method of manufacturing the image display device that make it possible to form pixels with a smaller number of sub-pixels as compared with a case where one pixel is formed so as to separately include one each of sub-pixels of three colors of R, G, and B, and make full-color display by making the sub-pixels emit light by time division. The present invention can provide an image display device that makes it possible to reduce the number of sub-pixels and form pixels at a high density by sharing respective sub-pixels between pixels and displaying the sub-pixels by time division and thus realize high picture quality and reduction in the number of parts.

An object of the present invention is to eliminate fluctuation in the value of the constant current I even if there is characteristic fluctuation in field effect transistors and at the same time, to improve the power consumption. There are provided with a plurality of current mirror circuits consisting of those on the reference side and on the mirror side; current holding capacitorsandprovided on the respective mirror sides of the plurality of current mirror circuits; sequential selection meansandfor selecting the plurality of current mirror circuits sequentially by a constant period; first switching meansandfor connecting respective reference sides and mirror sides of the plurality of current mirror circuits; reference voltage change-over meansandfor changing over reference voltages of constant current generation unitsandsuch that currents on the mirror sides become constant in conformity with the selection period of the plurality of current mirror circuits; and second switching meansandfor connecting the constant current generation unitsandto the reference sides of the plurality of current mirror circuits in conformity with the selection period.

Constant current drive device

An apparatus for adjustment and abnormality display includes a pseudo screen displaying unit for displaying each of a plurality of display units forming a display apparatus as a pseudo display unit according to position information of the display units; a selecting unit for selecting a specified pseudo display unit from the pseudo display units displayed; an adjusting information generating unit for generating information for adjusting the display unit corresponding to the pseudo display unit selected based on an adjusting operation; and an abnormality signal generating unit for generating an abnormality signal when an abnormality occurs in a display unit forming the display apparatus, wherein the selected display unit is adjusted by outputting the adjusting information to the display apparatus, and the pseudo display unit corresponding to the display unit having the abnormality is distinguishably displayed in the pseudo screen displaying unit based on the abnormality signal.
