Abstract: The present disclosure provides a quality control substance for use in the analysis of erythrocytes, which can be prepared safely with easily available raw materials, which has an excellent preservation stability, and which can be used in the analysis of sediments in a sample. This quality control substance includes artificial particles whose form as observed with a microscope is similar to the form of erythrocytes as observed therewith.

This quality control substance includes artificial particles whose form as observed with a microscope is similar to the form of leukocytes as observed therewith.

Abstract: A liquid crystal layer is disposed on a second glass substrate side between a first glass substrate and the second glass substrate, a first insulating film and a second insulating film are formed in this order on a surface of the first glass substrate on the liquid crystal layer side, the outer edge portion of the liquid crystal layer is surrounded by a sealing material, and a plurality of TFTs are insulated from each other by the first insulating film and the second insulating film. A gate insulating film included in the second insulating film is so formed as to have a higher barrier property for gas and/or liquid than the first insulating film, and a groove having a bottom formed with the same material as a part of the material for forming the TFT is formed at a part or the whole of a peripheral edge portion of the second insulating film which is located more inside than a position at which the second insulating film overlaps the sealing material.
