PROBLEM TO BE SOLVED: To provide a method for inspecting an electro-optical device, by which the product life of the device can be ensured in a highly accurate manner.SOLUTION: A method for inspecting an electro-optical device comprises: displaying an inspection image with an intermediate gradation on a display screen 200 by using a polarity inversion drive; measuring flicker values FLK of the inspection image at k number of measurement points (k is an integer of 2 or greater) of places on the display screen; calculating direct current component potentials Vfrom the flicker values FLK; and inspecting whether a first statistically processed result of the k number of the direct current component potentials Vsatisfies a first prescribed condition or not. In this way, a slight electrical asymmetry present in the electro-optical device is quantitatively evaluated. Accordingly, it is possible to provide an inspection method that is able to ensure the product life of the electro-optical device in a highly accurate manner. |
