Abstract

The present invention relates to a light source-guide structure having an LED as a light source and a backlight apparatus having the same. The light source-guide structure includes a light guide plate with grooves formed in a peripheral side thereof and a light source having a transparent package fitted into the groove of the light guide plate with an LED chip inside the transparent package. The structure also includes a wiring substrate for seating the LED chip and reflecting the light from the LED chip to the light guide plate and a reflection layer attached on upper surfaces of the light source and the light guide plate. With the light source inserted into the light guide plate, the loss of light is minimized while the horizontal beam angle of light from the LED is increased, minimizing the peripheral area.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2005-60782 filed with the Korean Intellectual Property Office on Jul. 6, 2005, the disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a backlight device having a light emitting diode (LED) as a light source. More particularly, the present invention relates to a light source guiding structure of a backlight device and a backlight device including the light source guiding structure, wherein a light source is located in a light guide plate to minimize loss of light incident from LEDs into the light guide plate, The amount of incident light is increased while increasing the horizontal beam angle of light emitted from the LED, thereby minimizing the peripheral area. Background technique [0003] Since a liquid crystal display (LCD) has no light source of its own, external lighting, usually a bac...
