A cabinet of a projection type display unit includes a base cabinet on which main component parts are mounted, and a top cover made from sheet metal which is mounted so as to cover the base cabinet, wherein a rear face portion of the top cover is formed in the shape of a curved surface being laid-down U-shaped in side view. The U-shaped curved surface is formed on an ergonomic basis, so that the rear face portion can be gripped securely even with one hand. On the back side of the top cover, bosses are integrally formed by use of a resin which is a different material from the sheet metal of the top cover, and the base cabinet and the top cover are fixed by fastening screws to the bosses from the base cabinet side.
