Abstract
Dummy filters which are irrelevant to displaying are arranged in a matrix consecutively with respect to color filter lines or columns close to a pouring opening. Although spacers move toward the pouring opening when the substrates are pressed for attachment, the moving spacers are stopped by and gathered around the dummy filters. This can prevent a pixel area from being adversely affected due to a light-less phenomenon.
