Title:
STRUCTURE PRODUCTION METHOD, COLOR FILTER PRODUCTION METHOD, SOLID STATE IMAGING ELEMENT PRODUCTION METHOD, AND IMAGE DISPLAY DEVICE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/179648
Kind Code:
A1
Abstract:
A structure production method including: coating a coloring photosensitive composition over a support provided with a plurality of regions divided by partition walls, to form a coloring photosensitive composition layer over the support including the interior of the regions divided by the partition walls; exposing the coloring photosensitive composition layer formed above the support to light in a patterned manner; and using a development solution to develop/eliminate the coloring photosensitive composition layer in the non-exposed portions, to form pixels in the interior of the regions divided by the partition walls. The development solution is formed from an alkali water solution containing 0.02 to 0.22% by mass of an alkaline agent and a chelator. Also provided are a color filter production method, a solid state imaging element production method, and an image display device production method, which comprise the structure production method.
