    摘要： An active matrix type display apparatus in which a plurality of pixel circuits each having an electroluminescent element EL, a 1st FET to control a current flowing in the EL, and a 2nd FET provided between a gate and a drain of the 1st FET are arranged in a matrix, the plurality of pixel circuits arranged in one direction are connected to a data line every column, the 2nd FET is turned on for a predetermined time period, and an image data current flowing in the data line is supplied to the gate and drain of the 1st FET, thereby writing a current value of the image data current. A preliminary charging circuit is connected to the data line. Before the writing operation in the predetermined time period is expired, a current of a predetermined current value is applied to the image data current so that a gate-source voltage of the 1st FET is equal to or larger than a threshold value. Thus, writing imperfection due to a variation in threshold voltage of the 1st FET is solved.

    摘要： In a display apparatus, second organic EL elements are closer to the edge of a display portion than first organic EL elements. The voltage drop in the first organic EL element is larger than that in the second organic EL element. The thickness of the organic compound layer in the first organic EL element is different from the thickness of the organic compound layer in the second organic EL element. The light-extraction efficiency in the first organic EL element is higher than the light-extraction efficiency in the second organic EL element.
