A radiograph viewer including a reflection sheet of a prism light guide panel for improving the luminance of a cathode ray tube is provided to maximize the efficiency of light generated in the cathode ray tube by forming the prism light guide panel of a transparent acrylic resin. A radiograph viewer including a reflection sheet of a prism light guide panel for improving the luminance of a cathode ray tube includes a back light unit and a prism light guide plate reflection sheet. The back light unit includes a reflection plate(50), a prism light guide plate(60), a diffusion sheet, a prism sheet, and a curtain tape. The prism light guide plate reflection sheet includes a reflection sheet. The reflection sheet is located at a lower portion of the prism light guide plate and reflects the light from the cathode ray tube to the front side to improve the luminance of the cathode ray tube. |
