BARRIER RIB STRUCTURE FOR DISPLAY DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To improve brightness and contrast of a display device such as a PDP as well as to recover and reuse grinding scarp after grinding. SOLUTION: A visible light absorbing material is included inside a translucent bulkhead so as to have a visible light absorbing distance of 40 to 1,200μm. Further, grinding scrap, by being recovered by the use of the same grinding material as a component included in a bulkhead-forming material, can be reused as a bulkhead material, thus manufacturing cost can be reduced.
