发明名称 LIGHT-EMITTING DEVICE, ELECTRONIC APPARATUS, AND SEMICONDUCTOR DEVICE DESIGN METHOD
摘要 PROBLEM TO BE SOLVED: To provide a light-emitting device, an electronic apparatus, and a semiconductor device design method capable of suppressing a variation in light emission luminance resulting from a variation in environmental temperature.SOLUTION: A light-emitting device including: a drive transistor TDR generating a drive current at a current amount in response to a gate-source voltage VGS; a light-emitting element E emitting a light at a luminance in response to the current amount of the drive current; and a data-line drive circuit 26 controlling the gate-source voltage VGS according to a designated gradation is configured as follows. The gate-source voltage VGS is a voltage of not less than a first voltage value for allowing the light-emitting element E to emit light at a luminance according to a first gradation and not more than a second voltage value for allowing the light-emitting element E to emit light at a luminance according to a second gradation. The first voltage value and the second voltage value are set such that a minimum-variation voltage value VGSm that is the gate-source voltage VGS when a change ratio (variation ratio NR) of the drive current relative to a change in an environmental temperature is equal to or smaller than a predetermined value falls within a range between the first voltage value and the second voltage value.
