Light guide plate, back light module and display apparatus
A light guide plate comprises a transparent light guide plate body; and a plurality of reflection sheets disposed inside the light guide plate body adjacent to a bottom surface of the light guide plate body, wherein a surface of the reflection sheet away from the bottom surface is configured as a reflection surface, regions of the light guide plate body except the reflection sheets are configured as light transmission regions, and the light transmission regions and the reflection sheets are alternately arranged. Since the reflection sheets are provided inside the light guide plate body, the reflection sheet reflects the light which is directed from the one surface and passes through the display panel, and prevents the light, which is directed from the other surface of the display apparatus, from passing through the display panel and interfering with the normal display of the one surface.

Back light unit with light guide plate preventing dark area between leds
A backlight unit with a light guide plate preventing the dark area between light emitting diodes (leds) is provided, wherein a plurality of dark area-preventing patterns formed on an incidence plane of a light guide plate and having different angles of inclination or different radii of curvature may evenly diffuse lights incident from an led even under the condition that the gap between the leds is relatively broad and greater than or equal to the width of an led and thus, uniform brightness may be obtained without an occurrence of a dark area. Accordingly, the number of the leds may be decreased and the backlight unit may be fabricated with a relatively low cost..
