<P>PROBLEM TO BE SOLVED: To provide an organic EL display device which performs display, by using self-luminous organic EL elements as pixels and arranging the elements in a matrix form, reduces the luminance variation of each pixel and has few sacrifices, even in terms of aperture ratio. <P>SOLUTION: The organic EL display device includes a luminescent section; a current control section for controlling the current to be passed to the luminescent section; a current detector for detecting the current value flowing in the luminescent section as a voltage; a first switching section for switching the transmission/non-transmission of the voltage value, corresponding to the detected current; a comparison amplifier for comparing and amplifying the voltage value transmitted from the first switching section and the voltage value, corresponding to an image signal; a second switching section for switching the transmission/non-transmission of the voltage value which is the compared and amplified result; and an image signal holding capacitor to be subjected to charging and discharging by the voltage value transmitted from the second switching section. The current control section controls the current to be passed to the luminescent section by the charging voltage of the image signal holding capacitor. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
