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

Strip sheet or rectangular sheet, their manufacturing method and liquid crystal display device technical field 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 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). The manufacture method of this frame-shaped double-sided adhesive tape comprises the following steps: Peeling sheet peeling process, the rol...

AI Technical Summary

Problems solved by technology

That is, there is a problem in that since the double-sided adhesive tape with 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 is increased.

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.
