Patent ID: 8517534

Claim:
A semi-finished blank for a varifocal lens, comprising: a first substrate; a second substrate that is opposite the first substrate; a first transparent conductive film produced on the front of the first substrate; a second transparent conductive film produced on the back of the second substrate; a varifocal section disposed between the first transparent conductive film and the second transparent conductive film; a first internal electrode that is connected to the first transparent conductive film; a second internal electrode that is connected to the second transparent conductive film; a first separation film, which is a separated partial region of the first transparent conductive film, is in a state of electrical non-contact with the first transparent conductive film, and is located opposite the second internal electrode connected to the second transparent conductive film; and a second separation film, which is a separated partial region of the second transparent conductive film, is in a state of electrical non-contact with the second transparent conductive film, and is located opposite the first internal electrode connected to the first transparent conductive film.
