Problems solved by technology

However, it is difficult to bond the two substrates with a sealing material, and once the panel is formed, it is difficult to allow the adhesive to penetrate and be placed between the narrow substrates outside the sealing material.

Embodiment Construction

[0044] Hereinafter, the lens before edging and the manufacturing method of the edging lens will be described with reference to the drawings. However, the technical scope of the present invention is not limited to these embodiments, and please note that it relates to the invention described in the claims and its equivalent inventions.

[0045] In addition, hereinafter, the blank lens and the finished lens (or the finished lens) are referred to as "lens before edging", and the lens that has been edged before edging is called an edging lens. In addition, the blank lens including the liquid crystal lens structure, the finished lens (or semi-finished lens), and the edging lens are collectively referred to as "liquid crystal lens".

[0046] figure 1 It is a partial schematic diagram of the electronic glasses 1 using an edging lens as an example.

[0047] Such as figure 1 As shown in (a), the electronic glasses 1 includes the glasses frame 2, the pile head 3, the hinge 4, the temple 5, the...

Abstract

Disclosed is a method for manufacturing an edging lens and a pre-edging lens whereby the cell gap in a liquid-crystal lens structure can be kept uniform with virtually no spacer material on the inside of the edging lens. Said pre-edging lens is characterized by having: a first transparent substrate; a second transparent substrate; a first sealing material into which a spacer material is not mixed; a liquid-crystal layer sealed in between the first transparent substrate, the second transparent substrate, and the first sealing material; and a second sealing material into which a spacer material is mixed. The second sealing material is disposed at a location that is outside the first sealing material between the first transparent substrate and the second transparent substrate and that is removed after edging.

Description

Technical field [0001] The invention relates to a lens before edging and a manufacturing method of the edging lens. Background technique [0002] Known glasses have a structure in which a lens having a coloring / decoloring mechanism that disappears the colored color by applying a predetermined voltage is inserted into the glasses frame, and is connected to a power supply separately provided in the glasses frame (for example, see Patent Literature 1). [0003] In addition, for large-sized liquid crystal cells, in order to prevent the appearance of dry color due to uneven cell thickness (cell thickness), a liquid crystal cell having multiple sealing walls provided with a sealing material mixed with spacers (for example See Patent Document 2). [0004] Furthermore, research and development of liquid crystal devices using flexible substrates made of, for example, plastics, etc. are particularly popular. In such a liquid crystal device, a liquid crystal panel having a structure in which...
