Embodiment 1

[0216] —Production of photosensitive transfer materials—

[0217] (1) On the surface of a polyethylene terephthalate film temporary support (PET temporary support) with a thickness of 75 μm, use a slit-shaped nozzle to apply and dry the composition described in the following Table 1. The photosensitive resin composition K1 is colored, and a black photosensitive resin layer is applied. Next, a protective film (polypropylene film with a thickness of 12 μm) was pressure-bonded on the surface of the black photosensitive resin layer to prepare a photosensitive transfer material. Hereinafter, it is called photosensitive transfer material K1.

[0218](2) The colored photosensitive resin composition K1 used in the preparation of the photosensitive transfer material K1 was replaced with the colored photosensitive resin composition R1, G1 or B1 having the composition described in Table 1 below, except Other than that, it carried out similarly to preparation of the said photosensitive ...

Embodiment 2

[0328] In Example 1, the height of the black (K) image was changed from 2.4 μm to 3.0 μm, and at the same time after the ITO film was formed, the following optical spacer (photospacer) was used further above the established K image. ) using a photosensitive transfer material as follows to form an optical spacer, and to produce a color filter side substrate in the same manner as in Example 1, and to fabricate a liquid crystal display device. In addition, in the present invention, the spacer structure in which the R pattern and the G pattern of Example 1 are stacked is not formed.

[0329] In addition, in the following "formation of the optical gap material", the degree of bleeding of the resin and the incorporation of air bubbles when the photosensitive transfer material for the optical gap material is laminated in two by the same method as in Example 1 Make an evaluation. The evaluation results are shown in Table 2 below. In addition, before forming the optical spacer, the l...

Embodiment 3

[0351] In Example 1, the height of the black (K) image was changed from 2.4 μm to 2.5 μm, and at the same time, after the ITO film was formed, the same optical spacer as in Example 2 was used on the top of the established K image. The photosensitive transfer material PH1 was carried out similarly to Example 1 except having formed the optical spacer similarly to Example 2, the color filter side board|substrate was produced, and the liquid crystal display device was produced.

[0352] In addition, in the "formation of the optical gap material", the degree of bleeding of the resin and the incorporation of air bubbles when the photosensitive transfer material for the optical gap material was laminated in two sheets was evaluated by the same method as in Example 1. . The evaluation results are shown in Table 2 below. In addition, before the formation of the optical spacer, the height difference of the substrate surface was 0.5 μm between the K image and the R pixel, G pixel, and B...

Abstract

A transfer apparatus is provided with at least a transfer mechanism for transferring a plurality of pieces of photosensitive transfer material (web) whereupon a photosensitive resin layer is formed directly on a temporal support; and a bonding mechanism for bonding the transferred pieces of web on a same board. In a method for manufacturing a laminated resin body, the photosensitive resin layers of the pieces of web are transferred on the same board without having them intersect each other by using such transfer apparatus.

Description

technical field [0001] The present invention relates to a resin laminate preferably used for producing a resin structure by a transfer method using a photosensitive transfer material having a photosensitive resin layer, a method for producing the same, a material for a display device using the resin laminate, and a display device and liquid crystal display devices. Background technique [0002] A photosensitive laminated material in which a photosensitive material layer such as a photosensitive resin layer is laminated on a substrate such as a glass substrate or a hard resin substrate is used as a resin laminate used in the production of a printed circuit board or a color filter. A liquid crystal panel is mentioned as an application of such a resin laminate, but one of the subjects of a liquid crystal panel is reduction of manufacturing cost. In particular, the color filter accounts for a high ratio of the cost of the liquid crystal panel, so increasing the yield of the col...
