An organic electroluminescence display device is provided having a display section including a plurality of pixels arranged in a matrix; and a detection section for detecting a luminance characteristic of an OLED element in each of the pixels. The detection section includes a first path for allowing a detected characteristic value to pass therethrough and a second path for attenuating the detected characteristic value. A first switch is provided for the first path whereas a second switch is provided for the second path, the second switch being opened when the first switch is closed. The detected characteristic value having passed through any one of the first path and the second path is input to a same analog-to-digital converter to be converted into a digital quantity.
