摘要： The present invention relates to a filter and a plasma display device thereof, wherein the filter includes an external light shielding sheet which comprises a base unit, and a plurality of pattern units that are formed on the base unit, wherein a bottom, which is wider than a top, of the pattern units is formed as a concave shape.
According to the present invention, the plasma display device of the present invention can effectively realize black images and enhance bright room contrast, as an external light shielding sheet, which absorbs and shields as much external light incident upon a plasma display panel PDP as possible, is disposed at a front of the plasma display panel. Also, the sharpness of the display images may be enhanced by reducing the bleeding phenomenon of the display images as well as the adhesiveness of the filter may be enhanced by forming the bottom of the pattern units of the external light shielding sheet as a concave shape in which the center area is depressed into the inside.
摘要翻译：本发明涉及一种滤光器及其等离子体显示装置，其特征在于，所述滤光片包括外部遮光片，所述外部遮光片包括基座单元，以及形成在所述基座单元上的多个图案单元，比上部的图案单元形成为凹形。根据本发明，本发明的等离子体显示装置可以有效地实现黑色图像并增强亮室对比度，作为吸收并屏蔽入射到等离子体显示面板PDP上的尽可能多的外部光的外部遮光片，设置在等离子体显示面板的前方。此外，可以通过减少显示图像的渗色现象来增强显示图像的清晰度，并且可以通过将外部遮光片的图案单元的底部形成为凹形来增强滤色器的粘附性中心区域被压入内部。
