COVER MEMBER FOR DISPLAYS, AND MANUFACTURING METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cover member for displays that can restrain unwanted appearance of the background in the intended image and has a high resolution level.SOLUTION: One main face 1a of a cover member 1 is configured of a convexo-concave face 2. The average inclination angle (θ) of the ruggedness curve of the convexo-concave face 2 is 0.5° to 1.5°. In the bearing curve of the convexo-concave face 2, (H-H)/Ra is 0.25 or greater where His the height when the area ratio is 70%, His the height when the area ratio is 99% and the arithmetically averaged ruggedness of the convexo-concave face as prescribed by JIS B0601-2013 is Ra.SELECTED DRAWING: Figure 1
