摘要： In order to suppress an influence of an electrical stress on a TFT characteristic in use of a TFT, a light emitting display apparatus according to the present invention comprises organic EL devices and driving circuits for driving the organic EL devices. The driving circuit includes plural pixels each having a thin film transistor of which a threshold voltage reversibly changes due to the electrical stress applied between a gate terminal and a source terminal, and a voltage applying unit which sets gate potential of the thin film transistor higher than source potential. The voltage applying unit applies the electrical stress between the gate terminal and the source terminal at a time when the thin film transistor is not driven, so as to drive the thin film transistor in a region that the threshold voltage is saturated to the electrical stress.

摘要： In a method of treating a semiconductor element which at least includes a semiconductor, a threshold voltage of the semiconductor element is changed by irradiating the semiconductor with light with a wavelength longer than an absorption edge wavelength of the semiconductor. The areal density of in-gap states in the semiconductor is 1013 cm−2eV−1 or less. The band gap may be 2 eV or greater. The semiconductor may include at least one selected from the group consisting of In, Ga, Zn and Sn. The semiconductor may be one selected from the group consisting of amorphous In—Ga—Zn—O (IGZO), amorphous In—Zn—O (IZO) and amorphous Zn—Sn—O (ZTO). The light irradiation may induce the threshold voltage shift in the semiconductor element, the shift being of the opposite sign to the threshold voltage shift caused by manufacturing process history, time-dependent change, electrical stress or thermal stress.
