Problems solved by technology

In this case, there is a problem that a part of the photosensitive resin composition layer is transferred to the cover film.
In addition, there is also a problem that this problem tends to occur gradually over time after the production of the photosensitive resin transfer material.

Abstract

The invention provides a fluorochemical light-sensitive resin composition containing repeating units represented by general formula (A), light-sensitive resin transfer material formed by using the light-sensitive resin composition, photospacer and manufacturing method thereof using them, and substrate for display unit having the photospacer and the display unit. In the general formula (A), R1 to R3 represent hydrogen atom or methyl, L1 to L3 represent -O- or -NH-, n and m represent an integral of 1 to 10, and m is not equal to n, l represent an integral of 1 to 5, X, Y and Z represent the mass ratio of each repeating units, X+Y=20 to 80, Z=80 to 20, X and Y are not simultaneously 0.

Description

technical field [0001] The invention relates to a photosensitive resin composition, a photosensitive resin transfer material, a photosensitive gap material and a manufacturing method thereof, a substrate for a display device, and a display device. Background technique [0002] Conventionally, liquid crystal display devices have been widely used as display devices for displaying images with high image quality. In a liquid crystal display device, generally, a liquid crystal layer capable of displaying images in a predetermined orientation is arranged between a pair of substrates. Maintaining the substrate gap, that is, the thickness of the liquid crystal layer uniformly is one of the factors that determine image quality. Therefore, a spacer is provided to keep the thickness of the liquid crystal layer constant. This inter-substrate thickness is generally referred to as "cell thickness". The cell thickness generally means the thickness of the liquid crystal layer, in other w...
