Embodiment 1

[0085]

[0086] Using a slit-shaped nozzle, the thermoplastic resin layer coating liquid formed from the following formulation H1 was coated on a polyethylene terephthalate film temporary support body having a thickness of 75 μm, and dried. Then, a coating liquid for an intermediate layer formed from the following formulation P1 was applied and dried. Further, the following colored photosensitive resin composition K1 was applied and dried, and a thermoplastic resin layer with a dry film thickness of 14.6 μm, an intermediate layer with a dry film thickness of 1.6 μm, and a dry film thickness of 2.2 μm were provided on the temporary support. The photosensitive resin layer is crimped with a protective film (polypropylene film with a thickness of 12 μm).

[0087] In this way, a photosensitive resin transfer material in which a temporary support, a thermoplastic resin layer, an intermediate layer (oxygen barrier layer) and a black (black) (K) photosensitive resin layer are integr...

Embodiment 2～14 and comparative example 1～7

[0166] A color filter was produced in the same manner as in Example 1 using the treatment liquids 2 to 14 and the treatment liquids 1 to 7 of the comparative examples.

[0167]

[0168] Due to the disadvantage of being difficult to reproduce SD consistently, the effect was judged by observing the extent to which the unexposed photosensitive resin layer that should be removed in the developing tank was removed for the pixel immediately after development. The effect is high at this stage, and there is no guarantee that in the actual manufacturing process of the color filter, if the contact of the SD brush or the like fluctuates due to various reasons, it is of course possible to manufacture the color filter with good quality.

[0169] The evaluation used an optical microscope to count the number of black (K) images formed in stripes per 200 μm in length. The measurement results are shown in Table 4. In addition, similarly, after the SD process, the number of black (K) images ...

Abstract

The present invention relates to a making method of the color filter in the making course of using the photosensitive transfer-printing material to the color filter, which makes the completed result that the visualization finishes improved and can make high-quality color filter even if the strict accuracy-management of the rotary brush is carried out. The invention relates to the treating liquid and the making method of the color filter which uses the treating liquid to remove the thermoplastic resin of the photosensitive transfer-printing material, the character of the treating liquid includes: it is the treating liquid which at least contains water and alkanolamine, and the content of alkanolamine relative to totality is 2 percent to 40 percent by mass, the alkanolamine contains triethanolamine and diethanolamine, the diethanlamine mass relative to the gross mass which contains the mass of diethanolamine and the mass of triethanolamine is 3 percent to 12 percent.

Description

technical field [0001] The present invention relates to a treatment liquid used in manufacturing color filters of display devices having color filters such as liquid crystal display devices, a method of manufacturing color filters using the same, and color filters and display devices manufactured by the method. Background technique [0002] Color filters used in liquid crystal display devices and the like have been developed in recent years centering on the method of coating a pigment-dispersed resist on a substrate. However, since the spin coating method or the like is used in this method, there is a problem that the loss of the pigment dispersion resist is large and the control of the conditions for uniform coating is difficult. As a solution to this, a method of using a photosensitive transfer material having a thermoplastic resin layer has been proposed (for example, refer to Patent Document 1). In this method using a photosensitive transfer material, since a photosensi...
