Abstract

PURPOSE:To suppress the warpage of the film substrate at the time of curing the substrate by UV rays or heat by using the film substrate contg. a photo- or thermosetting material as the substrate of a liquid crystal display device. CONSTITUTION:The film substrate 5 consists of a substrate formed by thinly stretching the curing resin which is a thermosetting resin or UV curing resin to a film form or a substrate formed by applying such curing resin to a flexible substrate of polyimide, etc., for example, polyimide, PVA, etc., or a substrate formed by stretching a mixture formed by mixing polyimide, PVA, etc., and the curing resin, to a film form. The film substrate 5 prior to formation of moldings, such as color filters 9 or switching elements, of the liquid crystal display device, on the film substrate 5 is wound on a take-up shaft 10 of the diameter as small as possible and after these moldings are formed, the film substrate 5 is taken up on a take-up shaft of the diameter larger than the diameter of the initial take-up shaft.

Furthermore, when a glass substrate is used, batch processing must be carried out for each glass plate of a certain size (for example, 30 cm × 30 cm), and it is not easy to handle, so it is not suitable for mass production. In addition, the cost ratio of the glass substrate to the liquid crystal display device is relatively high, which increases the manufacturing cost.

FIG. 6 is a view showing a film substrate manufacturing apparatus of the present invention. Normally, when winding a film-like material, it is better to wind the film substrate on the winding shaft with the smallest radius, because it is possible to wind many films on one winding shaft, which is advantageous in terms of normal cost. Therefore, the film substrate before forming the color filter or the switching element of the liquid crystal display device on the film substrate is wound on a film winding shaft as thin as possible, and the color filter or the switching device of the liquid crystal display device is placed on the film substrate. After forming the formed product, it is preferable to wind up the film substrate having a winding shaft thicker than the original winding shaft.

This is because when the film substrate, in which a color filter or a switching element of a liquid crystal display device is formed on the film substrate as in the present application, is wound around a winding shaft, the winding diameter is smaller than a certain diameter. When wrapped around the axis,
This is because the formed product such as the color filter or the switching element of the liquid crystal display device wound on the film substrate is curved by the winding, and the formed product is physically added.

When a color filter or a liquid crystal switching element formed on a film substrate is physically added to the color filter by winding, the color filter is made of a very soft material. If the liquid crystal switching elements are crushed and the color filters are mixed with each other to cause color misalignment, or if the switching elements are liquid crystal elements, the elements are destroyed and switching operations are not performed.

As a result of an experiment conducted by the inventor, it was found that the diameter of the winding shaft should be set to 1/6 or more of the length in the extending direction of one substrate in the case of later cutting. That is,
In the case of cutting every substrate by 30 cm in the manufacturing process, the film substrate of the present invention is wound around a winding shaft having a diameter of 5 cm or more.

Further, when the film substrate on which the color filter or the formed element such as the switching element of the liquid crystal display device is formed on the film substrate as described above and the film substrate is wound on the relatively thick winding shaft as described above, the film substrate is formed. The substrate is less likely to warp when cured by ultraviolet rays or heat. This is also a remarkable effect that occurs when the present application uses a resin that is cured by ultraviolet rays or heat as a film.
