ABSTRACT:
A liquid crystal display panel manufacturing method and an aligning apparatus for use in the method make it possible to precisely align an active matrix substrate and a counter substrate with high precision even if the two alignment marks thereon are substantially apart from each other. A clear image is formed by focusing a microscope onto an alignment mark on a counter substrate, captured into a video camera and output as a first image signal. The first image signal output from the video camera is temporarily stored in an image memory. Next, a clear image is formed by focusing the microscope onto an alignment mark on an active matrix substrate, captured into the video camera and output as a second image signal. The second image signal output from the video camera and the first image signal temporarily stored in the image memory are synthesized by an image synthesizing circuit, and then, displayed clearly on a monitor.
