PROBLEM TO BE SOLVED: To solve such a problem that, while a wearable display or a head mounted display has been miniaturized and reduced in weight in recent years, power consumption of a control circuit at the inside thereof is high, so that, if heat of a circuit element is efficiently dissipated to the outside, temperatures of a circuit component of the control circuit rise thereby to cause malfunctions of a device, failures of the circuit component or the like, resulting in the possibility of a deterioration in reliability.SOLUTION: A head mounted display includes a video display part, a control circuit for controlling a video signal projected on the video display part, a circuit element disposed in the control circuit, a substrate on which the circuit element is disposed, and a circuit part casing in which the control circuit is embedded, the head mounted display being combined with a lens part allowing a video projected on the video display part to be monitored. In the head mounted display, the control circuit and the video display part are disposed at a bent position, and a heat transfer plate extending from the control circuit to the lens part is provided.SELECTED DRAWING: Figure 2 |
