    摘要: An active matrix type display apparatus includes 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. The plurality of pixel circuits are arranged in a matrix and have every column connected to a data line. 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.
