A method and an apparatus for inspecting a display panel are characterized in that a height measuring means is provided, the height of a board plane including a liquid material applied part is discretely measured, while a board or the height measuring means is being shifted in a direction intersecting the liquid material, which is applied in a plurality of strips at prescribed intervals on the board, the height by the liquid material strip is extracted from a height shape signal obtained by making the obtained discrete height shape signals proximate, a series of the height signals are permitted to be inspection signals, and an application quantity of each liquid material strip is measured by the inspection signal. A manufacturing method using the inspection method and the inspection apparatus is also provided. A problem which caused continuous defects generated in an application process is rapidly detected by inspecting the status of the application process immediately after the fluorescent paste applying process to suppress the number of boards to be nonconforming products that cause a loss at minimum, and the process can be immediately recovered.
