MANUFACTURING METHOD OF LIGHT EMITTING DEVICE

摘要

PURPOSE: A manufacturing method of a light emitting device is provided to implement clean multiple gradation by reducing a current flowing between two electrodes. CONSTITUTION: A first pixel has a first light-emitting device and a first transistor. The first pixel has a second light emitting device and a second transistor. A wire supplies current to the first light emitting device and the second light emitting device. When video data is inputted to the first pixel, a current flowing in the first light emitting device of the first pixel is measured. A first current is remembered in the first memory of a memory unit. A second current is stored in the second memory of the memory unit.
