SIMPLE DISPLAY DEVICE FOR BACKLIGHT

PROBLEM TO BE SOLVED: To provide a display device that is simply constituted of as few components as possible, which is placed on a counter or a table for use. SOLUTION: An LED unit 21 is fixed on the bottom of a metallic holding frame 20 by using a thermal conductive double-sided adhesive tape while fixing an LED chip upward. Bolts 23 of pairs of supporting legs 22 are penetrated through and fastened by nuts 24 at both ends of the holding frame 20 in the longitudinal direction, and a light guide panel 10 and a metallic back panel 14 or the like on the back thereof are floated and supported to the holding frame 20 through a thermal conductive spacer 25. Also, a transparent panel 12 is removably arranged on the light guide panel 10 by a permanent magnet 31. Heat generated by the LED chip is dissipated by the holding frame 20 and the back panel 14, and also a display device A for backlight is obtained by removing the transparent panel 12 to thereby exchange a positive film.
