Definitions

  • the surface of the transparent substrate 10 may be entirely curved, or may be composed of a curved portion and a flat portion.
  • An example of a case where the entire surface is curved is a case where the cross section of the transparent substrate 10 is arcuate.
  • the transparent substrate 102 with a metal oxide layer has a printed layer 21 on the periphery of the second main surface 10b.
  • the printed layer 21 is, for example, a wiring circuit arranged near the outer periphery of a display device of a mobile device for the purpose of enhancing the visibility and aesthetic appearance of the display, or a bonding portion between the housing of the mobile device and the transparent substrate 102 with a metal oxide layer. etc. is provided to hide the
  • the peripheral portion means a belt-like region having a predetermined width from the outer periphery toward the central portion.
  • the printed layer 21 may be provided on the entire periphery of the second main surface 10b, or may be provided on a part of the periphery.
  • the width of the printed layer 21 can be appropriately set, for example, to a width capable of hiding the wiring circuit and the adhesive portion.
  • a desired color can be selected as the color of the printing layer 21 according to the purpose.
  • the print layer 21 is formed by a method of printing ink or the like.
  • the F/Si value measured on the second main surface 10b is preferably 0.08 or less, more preferably 0.05 or less, and the closer to 0, the better.
  • the F/Si value may be, for example, greater than 0. Since the antifouling layer can be formed, there is an advantage that the manufacturing process is simplified. When the F/Si value is within this range, the contact angle of the second main surface 10b can be reduced, and poor lamination with the display can be suppressed.
  • Step S102 is a step of bringing a part of the second main surface into contact with a jig and fixing the transparent substrate to the jig.
  • FIG. 6(a) is a schematic diagram showing how the second main surface 10b of the transparent substrate 10 is brought into contact with the jig 60 in step S102 to fix the transparent substrate 10.
  • the first main surface 10a is placed facing the raw material 61 of the metal oxide layer to be deposited in step S103.
  • no protective film is placed on the second principal surface 10b, and the second principal surface 10b is in direct contact with the jig.
  • the shape of the jig 60 is not particularly limited, and may be, for example, rectangular, circular, elliptical, or polygonal.
