Problems solved by technology

These spacer particles are randomly scattered on a transparent substrate such as a glass substrate. Therefore, if spacer particles are present in the pixel forming region, there are problems in that ghosting of the spacer particles occurs, or incident light is scattered and the liquid crystal display becomes unstable. Contrast reduction of components, etc.
However, the following problems have been pointed out: during the firing, the sublimation components in the radiation-sensitive resin composition sublimate, contaminating the firing furnace or the photomask.

preparation example Construction

[0164]

[0165] The radiation-sensitive resin composition of the present invention is obtained by uniformly mixing the [A] polymer, [B] polymerizable unsaturated compound, [C] radiation-sensitive polymerization initiator, and other optional ingredients in a predetermined ratio. prepared by mixing. This radiation-sensitive resin composition is preferably used in a solution state dissolved in an appropriate solvent.

[0166] The solvent used to prepare the radiation-sensitive resin composition of the present invention can be used: [A] polymer, [B] polymerizable unsaturated compound, [C] radiation-sensitive polymerization initiator, and other components optionally added. A solvent that dissolves and does not react with the ingredients. Examples of such solvents include the same solvents as those exemplified above as solvents that can be used for the production of the polymer [A]. These solvents may be used alone or in combination of two or more.

Synthetic example A1

[0204] In a flask equipped with a condenser tube and a stirrer, 5 parts by mass of 2,2'-azobisisobutyronitrile and 250 parts by mass of 3-methoxybutyl acetate were added, and 7 parts by mass of methacrylic acid, methacrylic acid tricyclic [5.2.1.0 2，6 ] 18 parts by mass of decane-8-yl ester, 15 parts by mass of styrene, 40 parts by mass of 3-methacryloxypropyltriethoxysilane and 20 parts by mass of glycidyl methacrylate and nitrogen replacement Then, while stirring gently, the temperature of the solution was raised to 80°C. The temperature was maintained for 5 hours to perform polymerization to obtain a solution containing 28.8% by mass of the copolymer (A-1). The weight average molecular weight Mw of this copolymer (A-1) was 12,000.

Abstract

The present invention provides a radiation-sensitive resin composition, a method for forming a spacer for a display element, an interlayer insulating film, and a display element. The spacers and interlayer insulating films of the display elements are formed at the sintering temperature of the display element. The radiation-sensitive resin composition of the present invention contains [A] polymer, [B] polymerizable unsaturated compound and [C] radiation-sensitive polymerization initiator, and is characterized in that: said [A] polymer contains (A1 ) a polymer having a structural unit having a carboxyl group and (A2) a structural unit represented by the following formula (1), and the [C] radiation-sensitive polymerization initiator includes a radiation-sensitive polymerization initiator having a hydroxyl group. (In formula (1), R 1 is a hydrogen atom or a methyl group; R 2 are each independently a hydrogen atom, an alkyl group having 1 to 6 carbons, an alkoxy group having 1 to 6 carbons, or a phenyl group; and n is an integer of 1 to 6).

Description

technical field [0001] The present invention relates to a radiation-sensitive resin composition. In detail, the present invention relates to a radiation-sensitive resin composition that can be suitably applied to a spacer or an interlayer insulating film of a display element. Background technique [0002] A display element represented by a liquid crystal display element is configured by combining various components. The present invention relates to a material suitable for a spacer and an interlayer insulating film therein. [0003] Conventionally, in display elements, spacer particles having a predetermined particle diameter have been used in order to maintain a constant distance between two transparent substrates. These spacer particles are randomly scattered on a transparent substrate such as a glass substrate. Therefore, if spacer particles are present in the pixel forming region, there are problems in that ghosting of the spacer particles occurs, or incident light is s...
