[0073] According to the first embodiment, the display device 1 of the embodiment of the present invention can be utilized by applying the property of emitting light directly to the user. More specifically, in a dark state, the light guide plate 20 is transparent and thus invisible, but if light is emitted from the light guide plate 20, a user (observer) can directly see the corresponding light. Therefore, it is significant that the transparency of the light guide plate 20 of the first embodiment exists in an invisible state when no light is supplied, and is visible only when power is supplied.

[0074] Such as Figure 5 As shown, when the display device 1 according to the embodiment of the present invention is a display device for a vehicle, the control unit (not shown) of the display device 1 controls to convey the state of the vehicle using the amount of emitted light from the light guide plate 20 . For example, when the light guide plate 20 is the rear glass G of the vehic...

Abstract

The invention relates to a display apparatus and a light guide plate. The display apparatus is characterized by comprising a light source and a light guide plate. The light guide plate includes: a light guiding part which guides light incident on a side thereof from the light source by total internal reflection; a fine pattern portion which emits the guided light only to an upper portion of the light guiding part; a guard ring portion which protects the fine pattern portion from the intrusion of impurities; and a light emitting member 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.

Description

technical field [0001] The present invention relates to a display device and a light guide plate, and more particularly, to a display device and a light guide plate that emit light in a single direction and is formed of a transparent material for protection from penetration of foreign objects. Background technique [0002] Transparent displays can be used in consumer electronics, transportation, industry, and military in the field of transparent devices, especially in the case of automotive windshields, to convey visual information, and can be matched with any form of glass to become an electronic display. device, thus enhancing the security system. [0003] In the case of a conventional light guide plate, in order to emit light in a single direction, it is necessary to provide an additional reflection plate in a direction opposite to the direction in which light is emitted, and this is because it is difficult to realize a transparent display. [0004] For this, it is neces...
