Artificial leather and light-transmitting device fabricated using the same

Artificial leather comprising:

• a fiber entangled body formed of ultrafine fibers having an average single fiber diameter of 0.1 μm or more and 8 μm or less;
• and
• an elastomer as constituent elements,
• wherein the artificial leather has a thickness of 0.4 mm or more and 1.2 mm or less and a weight per unit area of 80 g/m2 or more and 450 g/m2 or less, and one surface of the artificial leather is a design surface colored with a dye and/or a pigment and satisfies the following Formulas (1) to (3):
• L*1≤55 . . . (1)
• L0>50 . . . (2)
• ΔL* <−5 . . . (3)
• where L*1 is a lightness index (L* value) of the design surface in CIE1976L*a*b* color space, L*0 is a lightness index (L* value) of a surface opposite to the design surface in CIE1976L*a*b* color space, ΔL* is a difference (CIELAB 1976ab lightness difference, L*1-L*0) between the L* value of the design surface and the L* value of the surface opposite to the design surface, and the lightness index is a value measured under conditions of CIE standard light source D65 and a viewing angle of 10°, and
• wherein the artificial leather has a spectral transmittance of 0.2% or greater, where the spectral transmittance is measured in a band width of 5 nm and a region of 400 to 800 nm using a spectrophotometer V-770 Model (ISN-923 Model integrating sphere) manufactured by JASCO Corporation and Spectralon Reflectance Standard manufactured by Labsphere as a standard white plate.
