In optics, Newton's ring is a thin-film interference phenomenon, and its interference pattern is some concentric rings with alternating light and dark. In this application, "Newton's rings" refers to a display problem in which the display screen presents a ring of light and dark.
如图14和图15所示，第二隔垫物PS2可以由位于边框区BM的第一平坦化层1051和第二平坦化层1052形成，还可以仅由第一平坦化层1051或第二平坦化层1052形成，当然，还可以与显示区AA内的第一隔垫物PS1采用同一膜层同时形成。As shown in FIG. 14 and FIG. 15 , the second spacer PS2 may be formed by the
