ELECTRO-OPTICAL DEVICE, METHOD OF MEASURING CHARACTERISTICS OF ELECTRO-OPTICAL DEVICE, AND SEMICONDUCTOR CHIP

摘要

An electro-optical device includes: a display unit having a plurality of pixel circuits each including a driving transistor and a light emitting element that emits light depending on a current output from the driving transistor when a voltage is applied to a gate terminal of the driving transistor; and a test unit having a test unit connection switch connected to the gate terminal of the driving transistor of each of the pixel circuits, and a test voltage supply circuit connected to the gate terminal of each of the driving transistors through the test unit connection switch and configured to supply a test voltage to the gate terminal of each of the driving transistors when the test unit connection switch is turned on.
