FLEXOGRAPHIC PRINTING PLATE AND MANUFACTURING METHOD OF LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
Japanese Patent JP2020029003
Kind Code:
A
Abstract:
To provide a flexographic printing plate having high accuracy, no irregular thickness, no pinhole or the like, larger in thickness than conventional ones without largely changing printing conditions, and capable of forming a liquid crystal orientation membrane with thickness suitable as for a liquid crystal display element or the like, and a manufacturing method of the liquid crystal display element including a process for forming the liquid crystal orientation membrane by a flexographic printing method using the flexographic printing plate.SOLUTION: A flexographic printing plate 1 has a plate surface 3 for carrying inks having a rough surface with specific surface area Rof 4.3 to 6.0, unit space volume Sin a range of 12 μm/μmto 29 μm/μm. A manufacturing method of a liquid crystal display element includes a process for forming a liquid crystal orientation membrane using the flexographic printing plate by a flexographic printing method.SELECTED DRAWING: Figure 1
