Therefore, in order to prevent damage to the circuit components of the liquid crystal display device that have been subjected to shocks such as vibration or dropping, the metal mounting part must be strengthened without increasing the number of metal mounting parts. Means for increasing the plate thickness have been generally used, but this is not preferable because it increases the cost and weight.

めに最も効果的であるからである。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention can be practiced according to the form described in the claims, and is made of metal which is attached by screwing a screw such as a screw to a boss portion of an apparatus such as an electric apparatus to which a liquid crystal display device is mounted. In a liquid crystal display device having an attachment portion, the metal attachment portion has a bent portion formed by being bent laterally from a housing of the liquid crystal display device, and the bent portion is provided on the liquid crystal display device. By forming the reinforcing portion partially in a portion close to the housing, it is possible to prevent the metal mounting portion from being broken by a drop impact or a vibration impact, and to prevent the liquid crystal display device from being damaged. The reinforcing portion is provided partially at the bent portion of the metal mounting portion to reinforce the metal mounting portion with a minimum increase in weight. The reason why the reinforcing portion is provided at the bent portion of the metal attachment portion is that the bent portion is most effective for reinforcing.
