(Id. 6 (a)).

  Next, the sheet-like collective substrate 51 is punched by a Thomson press equipped with a cutting device in which a plurality of cutting blades formed in a straight line at the same interval as the width of the film liquid crystal cell 50 are mounted. The film liquid crystal cell 50 is cut to form a strip-like collective substrate 52. FIG. 6B shows one strip-like collective substrate 52.

  In order to make the strip-like collective substrate 52 into one film liquid crystal cell 50, it is placed on a cutting holding frame provided in a cutting machine.

  However, in the conventional film liquid crystal cell manufacturing method, the cutting blade used when cutting the rectangular sheet-like collective substrate into the strip-like collective substrate has an accuracy of a tolerance of ± 0.2 mm to ± 0.1 mm. However, the sheet-like substrate member has poor processing accuracy and has a tolerance of about ± 0.5 mm. Therefore, when the sheet-like collective substrate is formed into a plurality of strip-like collective substrates with a linear cutting blade, the length in the longitudinal direction may be a strip-like collective substrate having a length different by a maximum of 1.0 mm. When the individual ends of the strip-shaped collective substrates with different lengths are aligned, placed on the cutting holding frame, and cut to form individual film liquid crystal cells, the cutting blades form the film liquid crystal cells. There is a problem that the cut portion is cut by mistake.

  Accordingly, the present invention provides an apparatus for cutting a film liquid crystal cell, a holding frame for cutting, and a manufacturing method using the same, capable of accurately and reliably cutting a film liquid crystal cell formed on a sheet-like substrate member having low accuracy. The purpose is to provide.

  In order to solve this problem, in the apparatus for cutting a film liquid crystal cell according to the present invention, a sheet-like aggregate substrate in which film liquid crystal cells are formed in a matrix on a sheet-like substrate member is cut into a strip-like aggregate substrate in columns or rows. A plurality of cutting blades were arranged at equal intervals with the same width as the film liquid crystal cell. The cutting blade has a linear cutting part that cuts in the longitudinal direction and a positioning cutting part that forms a concave part and a convex part at the end of the strip-like aggregate substrate.

  Thereby, the strip-shaped aggregate substrate can be cut with the width of the interval between the cutting blades arranged at equal intervals, and when forming individual film liquid crystal cells, the concave and convex portions for alignment at the end of the strip-shaped aggregate substrate Can be formed.

  Further, in the holding frame for cutting a film liquid crystal cell of the present invention, the film liquid crystal cell was cut by a cutting apparatus for film liquid crystal cell having positioning cutting portions that form concave and convex portions at both ends in the longitudinal direction of the strip-shaped aggregate substrate. It has a frame part that supports both ends in the longitudinal direction of the strip-like collective substrate with two sides parallel to each other through the space part, and a positioning part is formed on the inner side of the frame part so as to face both ends of the strip-like collective substrate.

This is a film liquid crystal cell cutting holding frame provided with a length reference portion and a length adjusting portion that come into contact with the end side of the end portion of the strip-like collective substrate cut by the straight portion of the portion.

  Thus, when the strip-like collective substrate is an individual film liquid crystal cell, the length in the short direction of the strip-like collective substrate can be aligned by the width reference portion and the width adjusting portion, and the longitudinal direction is the length. Since the alignment can be performed by the reference portion and the length adjusting portion, the strip-like aggregate substrate can be placed on the cutting holding frame with high accuracy.

Abutting against the length reference portion and the width reference portion of the frame positioning portion, the strip adjustment substrate is placed on the inclined surface formed at the length adjustment portion and the width adjustment portion while being shifted along the strip-like assembly substrate. In this method, the substrate is cut and cut into individual film liquid crystal cells.

  As a result, the strip-shaped collective substrate is abutted against the length reference portion and the width reference portion provided in the positioning portion of the cutting holding frame, and is placed so as to shift the inclined surfaces of the length adjustment portion and the width adjustment portion. By doing so, since the error of the strip-like collective substrate formed with the accuracy of the tolerance of the cutting blade of the cutting device can be absorbed by the inclined surface, the strip-like collective substrate can be cut with high accuracy.

Since it can be placed so as to be orthogonal to two parallel sides, even when a plurality of strip-like collective substrates 9 are placed on the cutting holding frame 15, the longitudinal direction of each of the strip-like collective substrates 9. Can be aligned.

  Further, when the plurality of strip-like aggregate substrates 9 are placed on the cutting holding frame 15 by abutting the end sides of the strip-like aggregate substrates 9 against the length reference portion 28, Since the distance from the edge of the end portion to the cut portion of the film liquid crystal cell 7 can be made uniform, the strip-like aggregate substrate 9 can be accurately cut into individual film liquid crystal cells 7.
