Embodiment Construction

[0050] Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to the following embodiments.

[0051] It should be noted that in all of the following drawings, the dimensions, ratios, etc. of each component are changed as appropriate for the convenience of viewing the drawings. In addition, in the following description and drawings, the same reference numerals are assigned to the same or corresponding elements, and overlapping descriptions will be omitted.

[0052] In the following description, an XYZ rectangular coordinate system is set as needed, and the positional relationship of each member is demonstrated with reference to this XYZ rectangular coordinate system. In this embodiment, the width direction of the optical display member (liquid crystal panel) is defined as the X direction, and the direction perpendicular to the X direction in the plane of the liquid crystal panel (the conveyanc...

Abstract

This optical production method includes a cutting step in which an optical member (FS) is formed from an optical member sheet (FX). The cutting step includes a laser light irradiation step in which the optical member sheet (FX) is cut while moving a table (31) and a second cutting device (a scanner) relative to each other. The second cutting device moves relative to the table (31) along a light source relative movement path (Tr1), and laser light is emitted by the second cutting device toward the outside of the light source relative movement path (Tr1) in such a manner that a laser light movement path (Tr) follows a corner (C1) of a liquid crystal panel (P).

Description

technical field [0001] The invention relates to a production method of an optical display device and a production system of the optical display device. [0002] This application claims priority based on Japanese Patent Application No. 2012-175999 for which it applied to Japan on August 8, 2012, and Japanese Patent Application No. 2013-104404 for which it applied to Japan on May 16, 2013, and uses the content here. Background technique [0003] Conventionally, in the production system of optical display devices such as liquid crystal displays, optical members such as polarizing plates bonded to liquid crystal panels (optical display components) were cut from long optical member sheets so as to match the liquid crystal panels. After forming a substantially rectangular shape, it is bonded to a liquid crystal panel (for example, refer to Patent Document 1). [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2003-2...
