摘要： An optical head includes a plurality of unit regions repeatedly arrayed in one direction. Each region is constituted by a light-emitting element which is driven by a current to emit light, a control transistor which is connected in parallel with the light-emitting element, and which receives gray-scale data that specifies a high gray-scale level for the light-emitting element so as to be turned off and which receives gray-scale data that specifies a low gray-scale level for the light-emitting element so as to be turned on, and a driving transistor which is connected in series with the light-emitting element to generate a current. In each of the plurality of unit regions, a thermal resistance between the light-emitting element formed in the unit region and the control transistor formed in the unit region is smaller than a thermal resistance between the light-emitting element and a control transistor formed in a unit region adjacent to the unit region.
