Abstract
An electro-optical device includes a test circuit for testing drive of a plurality of pixel units and a plurality of test terminals that output inputted signals to the test circuit or that output signals inputted from the test circuit. The test terminals including a first test terminal input with a high frequency signal with a frequency higher than a frequency of a signal output from a second terminal. A third test terminal is interposed between the first test terminal and the second test terminal.
Claims5
