Abstract:
An organic EL device as an electrooptical device includes an organic EL element, a sealing member, a color filter, a dimension evaluation pattern, and a pedestal member. The organic EL element is disposed for each subpixel, in a display area of a base as a substrate. The sealing member includes a sealing layer that covers the organic EL element. The color filter is provided on the sealing layer. The dimension evaluation pattern is provided as an evaluation pattern for evaluating the color filter. The pedestal member is disposed between an end portion of the base and the sealing member. The dimension evaluation pattern is disposed on the pedestal member.
