Patent number: 8013807Abstract: A display apparatus includes a plasma display panel (PDP) having an upper substrate at which black matrices are disposed. The apparatus includes an external light shield having a panel side facing a display surface of the PDP and an opposing viewer side facing away from the display surface. The light shield includes a base unit and includes pattern units that absorb external light from the viewer side. The pattern units have boundaries defined by intersections of the pattern units and the base unit. The boundaries define widths of pattern tops disposed toward the panel side or the viewer side and define widths of pattern bottoms disposed toward the other of the panel side and the viewer side. A distance between a pair of adjacent black matrices is 4 to 12 times greater than a distance between adjacent boundaries, of a pair of adjacent pattern units, at adjacent pattern bottoms.Type: GrantFiled: September 14, 2007Date of Patent: September 6, 2011Assignee: LG Electronics Inc.Inventors: Hong Rae Cha, Ji Hoon Sohn, Sam Je Cho, Woo Sung Jang, Woon Seo Shin
