By the architectural feature of body 443, the light that first light source 422, secondary light source 424 and the 3rd light source 432 are sent produces total reflection in body 443 phenomenon is reduced, and is improved so produce the phenomenon of shade around the polygon support member 440.Though it should be noted that above-mentioned angle theta 1, θ 2, θ 3, is not limited thereto to 100 degree between 80 degree.Angle theta 1, θ 2, θ 3 are during more near the right angle, and total reflection phenomenon is low more, and angle theta 1, θ 2, θ 3 are preferably between 85 degree between 95 degree.Angle theta 1, θ 2, θ 3 can be any numerical value of avoiding light to produce total reflection in the exiting surface of polygon support member 440.
Dividing plate 450 is arranged on the substrate 410 along separator bar M.In this embodiment, the cross section of dividing plate 450 is a semicircle, and its middle section is perpendicular to the bottom surface 415 of substrate 410.Please refer to Figure 15, Figure 15 shows that the light intensity of the 3rd light source 432 in the S zone of Figure 14 is along the directions X variation diagram.Be subjected to blocking of dividing plate 450, pass separator bar M from the light of the 3rd light source 432 after, the intensity of the 3rd light source 432 promptly die-offs.Thus, the situation of light leak can be improved, and the image display quality of the display unit 1 (Fig. 2) of feasible utilization backlight module 400 further promotes.
Support member of the present invention is a plane in the face of the side of light source, and therefore the light from light source is passed support member smoothly, reduces support member and produces the situation of shade on every side, and then improve the image quality of display unit.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
