PROBLEM TO BE SOLVED: To prolong the service life of a liquid crystal panel by increasing the heat radiating effect by improving the heat conductivity of a case. SOLUTION: The liquid crystal panel 92 is housed in the case 91. Heat generated in the liquid crystal panel 92 is transmitted to the case 91. The case 91 consists of a metallic material and has a high heat radiating effect. Fins 121, 122 formed by disposing a plurality of linear projections at almost equal intervals are provided on the bottom surface of a frame 114. The fins 121 and 122 enlarge the surface area of the frame 114, and the high heat radiating effect is obtained. Thereby, the liquid crystal panel 92 sufficiently radiates heat, and its service life is prolonged.
