INTERMEDIATE MEMBER FOR LASER CONJUGATION AND CONJUGATION METHOD

摘要

PROBLEM TO BE SOLVED: To shade light such as a light source for back light with a conjugation part with securing waterproofness in the conjugation part by sufficiently enhancing conjugation strength of a member while avoiding melting and decomposition of a design layer.SOLUTION: An intermediate member for laser conjugation 40 has light transmissivity of wavelength of 400 nm or more and less than 800 nm of 30% or less, light transmissivity of wavelength of 800 nm to 1500 nm of 60% or more. A laser light is irradiated after layering the intermediate member for laser conjugation 40 with a second member 20. Then the laser light is irradiated to a design layer after layering the first member on which a laser light non-transmissive design layer and the intermediate member for laser conjugation 40.SELECTED DRAWING: Figure 3
