Title:
COATING-NOZZLE INSPECTION APPARATUS, INSPECTION METHOD AND COATING METHOD OF COATING LIQUID
Document Type and Number:
Japanese Patent JP2009160546
Kind Code:
A
Abstract:
To provide a coating-nozzle inspection apparatus which inspects whether a large number of fine coating liquid amounts formed in a coating nozzle are suitable, to be able to estimate suitability of a discharge amount, in an inspection method of the coating nozzle using for coating of a fluorescent material and a pigment material of a display device.
While a liquid is continuously discharged from a discharge opening 92 to form a column-like flow, light is cast 35, 36 to the column-like flow to measure the brightness of transmitted light. As the state of the transmitted light changes according to the diameter of the column-like flow, the difference of discharge amounts can be inspected by treating obtained information of the brightness.
