OPTICAL SUBSTRATE, METHOD OF MANUFACTURE AND LIQUID CRYSTAL DISPLAY ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To solve the problem that in a conventional UV irradiation method and a plasma treatment method, a large amount of energy is required and as a result a resin layer is deteriorated and the reduction of optical characteristics such as discoloration of the resin layer and the reduction of the adhesion properties of the resin layer are generated. SOLUTION: This optical substrate is characterized in that the substrate consists of at least a resin layer and is formed by irradiating the substrate with UV having <=200 nm wavelength so that the substrate has <=50 deg. contact angle with water on its surface and <=5% variation of transmittance of light having 400 nm wavelength before and after the UV irradiation.
