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, with reference to the drawings, the lens before edging and the method of manufacturing the edging lens will be described. However, the technical scope of the present invention is not limited to these embodiments, and attention should be paid to the contents of the inventions described in the claims and equivalent inventions thereof.

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

[0046] figure 1 It is a partial schematic view of the electronic glasses 1 using edged lenses as an example.

[0047] Such as figure 1As shown in (a), the electronic glasses 1 include a spectacle frame 2, a stud (ヨロイ) part 3, a hi...

Abstract

It is an object of the present invention to provide a lens before edging and a method for manufacturing the edging lens in which the cell thickness of the liquid crystal lens structure can be kept constant without substantially containing a spacer inside the edging lens. It is characterized in that it has: a first transparent substrate; a second transparent substrate; a first sealing material without gaskets; a liquid crystal layer sealed between the first transparent substrate, the second transparent substrate and the first sealing material; And the second sealing material mixed with the spacer is arranged outside the first sealing material between the first transparent substrate and the second transparent substrate and is cut off after edging.

Description

technical field [0001] The invention relates to a lens before edging and a method for manufacturing the edging lens. Background technique [0002] Known spectacles have the following structure: a lens with a coloring / decolorization mechanism that makes the colored color disappear by applying a prescribed voltage is embedded in the spectacle frame, and is connected to a power supply that is separately configured in the spectacle frame (for example, refer to the patent document 1). [0003] In addition, for a large liquid crystal cell, there is known a liquid crystal cell in which a plurality of sealing walls are provided with a sealing material mixed with a spacer in order to prevent interference color caused by uneven cell thickness (for example, See Patent Document 2). [0004] Furthermore, research and development of liquid crystal devices employing flexible substrates made of plastic, for example, are particularly active. In such a liquid crystal device, a liquid cryst...
