    • PROBLEM TO BE SOLVED: To provide a printing plate for letterpress reversing offset printing which is capable of suppressing a breakage of a pattern due to clearing in midsection, while maintaining a dimensional accuracy of the pattern, and to provide a manufacturing method of a liquid crystal display device using this printing plate and the liquid crystal display device.
      SOLUTION: In the printing plate 6 for letterpress reversing offset printing, a necessary pattern part corresponding to the pattern to be transferred to a substrate is a recess, while an unnecessary pattern part corresponding to the pattern not to be transferred to the substrate is a projection. An auxiliary pattern 9 formed to be at least one projection pattern is provided inside at least one necessary pattern part of the printing plate 6. The breakage of the pattern called nakanuke (clearing in midsection) caused by the ink 5 of a blanket 1 that comes into contact with the bottom of the necessary pattern part of a large area and remains there can be suppressed by this auxiliary pattern 9, and even in the case when both of a high-precision pattern and a large-area pattern are present, the patterns can be formed by using the printing plate 6.

    • 要解决的问题:提供一种能够在保持图案的尺寸精度的同时抑制由于中部清理而导致的图案破损的凸版反转胶版印刷版,并且提供一种制造方法 使用该印版的液晶显示装置和液晶显示装置。 解决方案:在用于凸版反转胶版印刷的印版6中,对应于要转印到基板的图案的必要图案部分是凹槽,而对应于不转印到基板的图案的不需要的图案部分 是一个投影。 形成为至少一个突起图案的辅助图案9设置在印版6的至少一个必要图案部分的内部。由来自毯子1的墨5引起的称为nakanuke(中部清理)的图案的断裂 与大面积的必要图案部分的底部接触,并且保留在该辅助图案9中可以抑制,并且即使在存在高精度图案和大面积图案的情况下,图案 可以通过使用印版6形成。版权所有(C)2008,JPO&INPIT
