The invention has its object to provide a highly reliable dot matrix display which is free from the trouble of work of connecting the leads comprising the wire harness and the like between the dot matrix modules to be displayed in parallel arrangements, and which does not show disconnection even in case of occurrence of vibration. The dot matrix display comprises a plurality of parallel arrangements of the dot matrix modules which have a luminous section provided in matrix form, and a drive section for controlling the display contents in the module. And, there are provided on the respective module a light emitting element and a light receiving element which can send and receive the display signal between the adjacent modules in case of the transmission of the display signal based on each module from the end part of the modules in parallel arrangement.
