| description | To provide a display device and a light guide plate which emit light unidirectionally, are made of a transparent material, and protect themselves from intrusion of external impurities.SOLUTION: A display device 1 includes a light source 10 and a light guide plate 20. The light guide plate includes: a light guiding part 21 which guides light incident on a side thereof from the light source by total internal reflection; a fine pattern portion 22 which emits the guided light only to an upper portion of the light guiding part; multiple guard rings 24a, ... which protect the fine pattern portion from intrusion of impurities; and a light emitting member 23 which is disposed on a top surface of the fine pattern portion and a top surface of the guard ring portion. The light guide plate is formed of a transparent material.SELECTED DRAWING: Figure 2a
【課題】単方向に出光し、透明材質で具現されて外部不純物の浸透から保護するために具現されたディスプレイ装置及び導光板を提供する。【解決手段】ディスプレイ装置１は、光源１０及び導光板２０を含む。導光板は、光源から側面に入射された光を内部全反射によってガイドする導光部２１、ガイドされた光を導光部の上部へのみ出光させるように具現された微細パターン部２２、微細パターン部を不純物の浸透から保護するための複数のガードリング２４ａ・・・及び微細パターン部とガードリングの上面に配置された出光部材２３を含む。導光板は、透明材質で具現された。【選択図】図２ａ |
