An image display apparatus includes a hermetic container and an image display member arranged in the hermetic container. The hermetic container is provided with a first substrate, a second substrate arranged to be opposed to the first substrate, and an outer frame arranged between both of the substrates. The first substrate includes an aperture through which an electric power supplying terminal penetrates to the image display member. The aperture is sealed by a sealing member guiding the electric power supplying terminal to an outside of the hermetic container. The sealing member is adhered on a back surface of the first substrate. The back surface is opposite to a surface of the first substrate, on, which the outer frame is arranged. An electroconductive member is arranged between the sealing member and the back surface. The electroconductive member is at predetermined electric potential.
