Disclosed herein is an active-matrix display apparatus, wherein if any particular one of N light emitting sub-devices pertaining to any specific one of pixel circuits is defective, the particular light emitting sub-device is electrically disconnected from the specific pixel circuit and the magnitude of a driving current supplied to the (N−1) remaining light emitting sub-devices pertaining to the specific pixel circuit is adjusted so that the (N−1) remaining light emitting sub-devices receive a driving current from a device driving transistor with a magnitude suppressed to a value equal to ((N−1)/N) times the magnitude of a driving current which is supplied to a normal pixel circuit not including a defective light emitting sub-device.

A method of producing a display device includes the steps of forming gate electrodes on a substrate so that an arrangement of a source and a drain, in a pixel row direction, of a thin-film transistor formed in each of pixels on the substrate is reversed every pixel row; forming a gate insulating film and an amorphous semiconductor thin film on the substrate in that order so as to cover the gate electrodes; crystallizing the semiconductor thin film by irradiating the semiconductor thin film with an energy beam so that a scanning direction of the energy beam is the same with respect to the arrangement of the source and the drain in the pixel row direction; and forming a light-emitting element connected to the thin-film transistor.

The invention provides a pixel circuit that allows simultaneous correction of both influence of the threshold voltage of a drive transistor and influence of the mobility of the drive transistor. Correction means is connected to a drive transistor and a capacitance part, and operates during a correction period preceding to a sampling period. The correction period is separated into a reset period and a detection period. During the reset period, the correction means energizes the capacitance part to reset the potential of the capacitance part. During the detection period, the correction means stops the energization and detects the potential difference arising between the source and gate of the drive transistor during the period when a transient current flows through the drive transistor. The capacitance part holds the potential corresponding to the detected potential difference. The held potential includes both a potential component for reducing the influence of the threshold voltage on the output current of the drive transistor, and a potential component for reducing the influence of the carrier mobility thereon.

Disclosed herein is a display device including: a pixel array unit having pixel circuits arranged in a form of a matrix; and a control unit having a writing scanning unit for outputting, to the sampling transistor, a writing scanning pulse. The control unit effects control to supply a control input terminal of the drive transistor with a fixed potential for a threshold value correcting operation for retaining a voltage corresponding to a threshold voltage of the drive transistor in the storage capacitor. When setting a voltage across the storage capacitor to the threshold voltage of the drive transistor by repeating the threshold value correcting operation a plurality of times on a time division basis, the control unit effects control to perform each the threshold value correcting operation and the sampling transistor to a conducting state.
