PROBLEM TO BE SOLVED: To provide a liquid crystal display device high in display quality and easily exchangeable of a cold cathode tube by preventing the noise of a display image caused by radiation voltage generated from the cold cathode tube, and preventing the irregularity of the display image caused by the heat generated by the cold cathode tube. SOLUTION: The cold cathode tube 3 is arranged oppositely to the side face of a transparent light guide plate 4 made of an acrylic plate, etc., by holding the cold cathode tube 3 by lamp angles 8 fastened together with a metallic backlight angle 9 to a resin base plate 2 by screws 10. A lamp reflector 5 made of PET, etc., are attached to the inner wall surface of the lamp angles 8, and an optical sheet and a reflecting sheet 7 made of PET, etc., are attached to the front and back surfaces of the light guide plate 4 respectively. Moreover, the backlight angle 9 is grounded through a substrate on which electronic parts are provided. |
