Description of the invention (2) The crystal exhibits a birefringence effect, because the liquid crystal has a positive birefringence (positive birefringence) ), That is, parallel light has a refractive index (extraordinary refractive index: ne) that is greater than the vertical refractive index (ordinary refractive index: no), so that light has a phase retardation effect when passing through it. However, if you want to avoid this problem To produce a wide viewing angle effect for a liquid crystal display, an optical film with a negative refractive index can be used as a wide viewing angle film to make it have optical symmetry with the liquid crystal display, and Achieving the effect of compensating contrast and color. At present, it is known as an optical film layer that can be used as a wide viewing angle film. Although it has applicable optical properties, its chemical solvent has good corrosion resistance, and its adhesion to the surface of optical elements is poor. Therefore, in the application of optical element technology, it is necessary to further cooperate with the surface treatment process, which often complicates the process. There are not many materials used as optical thin films. For example, ancient plastic films, although they have physical properties such as chemical solvent resistance, suitable for thermal formation and high weather resistance, but they exhibit high & It is difficult to achieve coordination between its physical characteristics and its optical characteristics. As for the purpose: 'Generally known to have color' 0 This is not suitable for optical applications. A coating composition for forming optical films is also used. According to the disclosure, the main purpose is to form a film layer on the optical element as a protective layer of the optical element. The coating composition contains two to three reactive functions (functlnanaty). Isooctyl attack

Invention Description (12) Properties, adhesion and weather resistance. Furthermore, when the hardened layer of the photocurable coating composition according to the present invention is formed on a substrate, the product phase difference is not too far from that of the substrate on which the hardened layer is not formed. The so-called product phase difference is a measure of the optical properties of the product. It means that when light passes through the product, it is moved in two perpendicular projection directions. Its value is equal to the birefringence (△ "product of the product's birefringence). If the phase difference is smaller, it means that the light passes through the product before and after the position: the smaller the value. At present, the measured phase of the product obtained according to the present invention is cold. Provided that: t η " Compared with conventional technology " The hardened layer of the light-curable coating composition according to the present invention has a very low birefringence system. Even more, although the present invention has been limited to the present invention by preferred embodiments Anyone who is familiar with this technique = expose; 上: above is not intended to be used within the scope, and can be modified in various ways without departing from the spirit of the present invention, as determined by the scope of the appended patents ^ the present invention Protection
