[0037] Production of Resin Letterpress

[0038] First, a glass plate with a thickness of 10 mm is prepared. A negative film was placed thereon, and a liquid photocurable resin (manufactured by Asahi Kasei Co., Ltd., APR) was applied to a certain thickness on the negative film with a doctor blade coater. After that, the base film was placed on the surface of the above-mentioned photocurable resin. Then, light is irradiated through the base film, and then light is irradiated through the above-mentioned negative film to form protrusions for printing, and at the same time, a plurality of microprotrusions and grooves formed by the microprotrusions are formed on the protrusions for printing. After that, the uncured resin is washed and removed, dried and exposed to light (post-exposure) to produce a resin relief.

[0039] In addition, the negative-type film used in the production of the above-mentioned resin relief is produced by a...

Abstract

PURPOSE: To provide a resin relief printing plate for forming a thin film by which a marginal phenomenon is prevented from being generated and an oriented film with a uniform film thickness can be formed. CONSTITUTION: In the resin relief printing plate for forming the thin film used for transferring a coating liquid applied on projected parts 2 for printing onto a body to be printed and printing, channel parts 4 for holding the coating liquid are formed among adjoining micro-projections 3 by distributing and forming a number of the micro-projections 3 on the whole face of the projected parts 2 for printing. In addition, in the central regions X of the projected parts 2 for printing, the adjoining micro-projections 3 are uniformly formed and in the peripheral regions Y of the projected parts 2 for printing, distribution densities of the micro-projections 3 are higher than those of the central regions X. In addition, the occupied area ratio of the micro-projections 3 becomes gradually higher as the regions approach toward the end parts in the peripheral regions Y.

Description

technical field [0001] The present invention relates to a resin relief plate for thin film formation capable of forming an alignment film having a uniform thickness on an electrode formation surface of a substrate for a liquid crystal display element. Background technique [0002] Resin letterpress is used for various printing. In particular, in recent years, when producing a liquid crystal display device, a letterpress printing method using a resin relief plate has been used in order to print an alignment film forming an alignment layer. Specifically, in order to print and form an alignment film made of polyimide resin on the surface of a glass substrate, a resin relief plate made of a photocurable resin is generally used. Then, using the above-mentioned resin relief plate, prepare two glass substrates printed with an alignment film made of polyimide resin, and laminate the polyimide resin alignment film against each other to produce the above-mentioned polyimide resin ali...
