An illumination device and a manufacture method thereof are provided. The illumination device includes a base, an illumination chip, and a sealant. The base has a surrounding side wall which encloses a containing space. The illumination chip is disposed within the containing space while the sealant fills the containing space and covers the illumination chip. The sealant has an outer surface which includes a center concave and a circular convex surrounding the center concave. The center concave is formed as a part of a spherical surface with no singular point. The connection between the center concave and the circular convex forms a circular ridge.

A backlight module includes a light guide plate, at least one first lighting element, and at least one second lighting element. The light guide plate has a first side surface and a second side surface opposite the first side surface. The first lighting element is disposed on the first side surface and has at least three light emitting diodes of different colors. The second lighting element is disposed on the second side surface and has at least three light emitting diodes of different colors. The arrangement of the light emitting diodes of the first lighting element is different from the arrangement of the light emitting diodes of the second lighting element.

A backlight module unit and a backlight module are provided. The backlight module unit includes a first light source, a second light source, and an optical barrier. A light source interval is defined between the first light source and the second light source, while a barrier interval is defined between the optical barrier and the second light source. Because the barrier interval is substantially shorter than a half of the light source interval, the backlight module unit mixes the light evenly, and prevents the dark bands from forming due to the disposition of the optical barrier. Thereby, the backlight module that comprises the plural aforesaid backlight units will have no dark bands, mix light evenly, and be thin overall.

A diffuser used in a backlight module including a plurality of light sources is disclosed. The diffuser according to the present invention makes a uniform light output. The diffuser includes a transparent substrate and a plurality of optical structures. The transparent substrate has an entrance surface and an exit surface. The plurality of optical structures is disposed on the exit surface, each optical structure is dented from the exit surface to the interior of the transparent substrate and forms a refractive convex within the transparent substrate, and each refractive convex corresponds to one of the plurality of the light sources. The maximum value of the included angle between the tangent to the refractive convex edge and the normal to the exit surface is smaller than 30 degrees, such that an incident light ray from the light sources refracts and deviates from the normal to the refractive convex through the refractive convex.

This present invention discloses a backlight module including a frame and a light guide plate. The frame includes a base plane and a side wall, wherein the side wall is disposed at the edge of the base plane and encloses a disposition space. The side wall includes a first inner surface and an outer surface, wherein a distance between the first inner surface and the outer surface is decreased as the first inner surface comes closer to a bottom of the side wall. The light guide plate is disposed on the base plane and within the disposition space, wherein the first inner surface sinks toward the outer surface and a recessed space is formed between the first inner surface and a lateral side of the light guide plate.

A backlight module, a liquid crystal display using the backlight module, and a manufacturing method thereof are provided. The backlight module includes a bottom plate, a plurality of light source sets and at least one partition wall. A plurality of lighting areas is formed on the bottom plate and light source sets are disposed on the lighting areas, respectively. The partition wall is disposed on the bottom plate and between each two adjacent lighting areas to fully or partially block/reflect the light emitted from the lighting areas. The partition wall includes a first light-penetrable wall and a light reflective layer formed on a wall surface of first light-penetrable wall. The light reflective layer is erected on the bottom plate through the support provided by the first light-penetrable wall and its wall surface.
