LIGHT SOURCE-GUIDE STRUCTURE OF BACKLIGHT APPARATUS WITH LED LIGHT SOURCE INSERTED INTO LIGHT GUIDE PLATE AND BACKLIGHT APPARATUS HAVING THE SAME

摘要

A light source-light guide plate structure of a backlight device in which an LED light source is inserted into a light guide plate, and a backlight device including the same are provided to increase the intensity of an incident light by minimizing light loss when a light enters the light guide plate from an LED by inserting the LED light source into the light guide plate, and minimize an edge area by increasing a horizontal direction orientation angle of the light emitted from the LED. A light guide plate(110) has grooves(114) formed at a side, crossing thickness. An LED(Light Emitting Diode) light source is combined with the light guide plate, and includes LED chips(134) arranged in a transparent package and a wiring substrate(132) reflecting a light generated from the LED chips to the light guide plate. A reflector layer is attached to an upper side of the LED light source and an upper side of a side of the light guide plate to which the LED light source is inserted.
