Strip sheet and rectangle sheet, manufacturing method thereof and liquid crystal display device

Abstract

The invention provides a manufacturing method of strip sheets stuck with approximately frame-shaped double-side agglutinate adhesive tapes which can reduce the abandoned amount of the double-side agglutinate adhesive tapes, comprising the following working procedures: in the first working procedure, a strip sheet (A) stuck with more than two double-side agglutinate adhesive tapes in parallel and a rectangle sheet (C) stuck with more than two double-side agglutinate adhesive tapes in parallel are crossed so that the faces of the double-side agglutinate adhesive tapes are mutually opposite and the crossed angle is about 90 degrees; in the second working procedure, the rectangle sheet (C) is pressed on the strip sheet (A); in the third working procedure, two adjacent double-side agglutinate adhesive tapes of the strip sheet (A) and two adjacent double-side agglutinate adhesive tapes of the rectangle sheet (C) form an approximately #-shaped double-side agglutinate adhesive tape; an approximately O-shaped incision is cut at the middle part of the external circle and the internal circle of the approximately O-shaped part of the approximately #-shaped double-side agglutinate adhesive tape; in the fourth working procedure, the part with the external side of the incision is removed from the rectangle sheet (C).

Description

technical field [0001] The present invention relates to a method for manufacturing a long sheet of a substantially frame-shaped double-sided adhesive tape used for manufacturing small to medium-sized liquid crystal display devices such as mobile phones, portable game machines, and digital cameras and components thereof, A long sheet or a rectangular sheet of a substantially frame-shaped double-sided adhesive tape, and a liquid crystal display device in which components are bonded by the substantially frame-shaped double-sided adhesive tape. Background technique [0002] A method for producing such a frame-shaped double-sided adhesive tape is disclosed, for example, in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2005-126643). [0003] The manufacture method of this frame-shaped double-sided adhesive tape comprises the following steps: [0004] Peeling sheet peeling process, the roll releases the double-sided adhesive tape with the peeling sheet ...

AI Technical Summary

Problems solved by technology

That is, there is a problem that, since the double-sided adhesive tape having the size of the display window of the liquid crystal screen is removed, the waste amount of the double-sided adhesive tape which is the main material of the frame-shaped double-sided adhesive tape is large, and the production cost increases.

And there is also the following problem: Since each side of the frame shape is originally formed by the same double-sided adhesive tape, the four corners of the frame side of the frame-shaped double-sided adhesive tape are connected, and the characteristics, shape, and material of each side cannot be changed. Unable to meet different requirements for each frame

For example, there is a problem that it is impossible to make one frame edge white and reflect light, and the other frame edge is black to block light, etc.
