PROBLEM TO BE SOLVED: To provide a module per se a structure of a thin panel and simplify a wiring on the back greatly when a multiplicity of modules are combined to constitute a big screen, thus providing panel type LED display modules which can be made easily and put up on a wall of a building with fewer parts and assembling processes at low cost. SOLUTION: On a front side of a printed circuit board 1, a plurality of integrated circuits to drive a lamp are loaded in the space of each pixel lamp 7 and two signal cables 13.14 connected to them by a circuit are laid to the bottom of the printed circuit board 1. The space located at the bottom of the circuit board 1 of a panel-type case 2 is for accommodating the signal cable 13.14 fitted with connectors. When a multiplicity of modules of the same configuration are laid out lengthwise and crosswise, a transmission way for a display data signal and for a control signal is created by cross-connecting connectors of signal cables of adjoining modules.
