Abstract
An optical element for a display device that can be placed on the head of a user and generate an image as a virtual image. The optical element having a first part, which comprises an optically effective structure, and a second part connected to one another by an adhesive composition comprising a ultra material. The first part material comprises one or more cycloolefin polymers, the first and third material are different from one another, and the second part material and third material in each case comprise at least one organic polymer. The refractive index differences for at least one wavelength between 380 nm and 800 am between the first and the second material and between the second and the third material are in each case ≤0.02. The method of producing the optical element and the display device comprising the optical element are also provided.
