An electro-optical device includes an electro-optical panel and a frame configured to support the electro-optical panel. The electro-optical panel includes a first member being a translucent substrate body, a second member being a translucent film and opposed to the first member, and pixel electrodes provided at an opposite side from the first member with respect to the second member. Lens surfaces having a protruding curved surface and each overlapping, in plan view, with each one of pixel electrodes are formed at a surface of the second member that is opposed to the first member. Since an inlet passage and an outlet passage, each of which communicates with the space, are formed between the first member and the second member, a refrigerant is caused to pass through the space by way of the frame, whereby it is possible to cool the electro-optical panel.
