Filter and flat panel display device using the filter |
| 摘要 |
<p>A flat panel display device includes a display panel and a filter which is disposed at a front of the display panel and includes an external light shield layer. A base unit of the external light shield layer satisfies the following equation: 1.5 × h3 <h4 <2.0 × h3 where h3 indicates a drop height of a steel ball having a weigh of 5 - 9 g to generate a crack in a filter including no impact-resistant layer and h4 indicates a minimum drop height of the steel ball that can result in a crack in a filter including the impact-resistant layer. Therefore, the durability of the filter or the display panel against an external impact can be improved.</p> |
