Abstract

An image display device which suppresses destruction of an image display panel due to static electricity carried by a phase difference film, and has excellent adhesiveness between the phase difference film and the image display panel even in a moisture-heat environment, and a circularly polarizing plate with a photosensitive adhesive. The image display device includes a circularly polarizing plate having a linear polarizer and a phase difference film, and an image display panel in this order from a viewing side, in which the phase difference film and the image display panel are bonded by a pressure-sensitive adhesive, the phase difference film has an optically anisotropic layer obtained by polymerizing a polymerizable liquid crystal composition containing at least one kind of polymerizable liquid crystal compound having a predetermined structure, and the pressure-sensitive adhesive contains a polymer having an acid value of 1 to 30 mgKOH/g and an antistatic agent.
