To aim at improving assembling efficiency and cost reduction at least in an electric-connection process related with a preparation method of a sheet-formed EL element display device to display prescribed information and an EL element display module.

This is the EL element display module 21 wherein an EL element forming part 23 and a connecting terminal 24 are formed on a substrate 22 for display and wherein a pressure-sensitive adhesive 25 is applied to either of these, and when the EL element display module 21 is loaded in an electric connection with a prescribed pattern 13 formed on the substrate 12 for the device to constitute the EL element display device, this module is constituted so that a corresponding pattern 13 on the substrate 12 for the device and a connecting terminal 24 of the EL element display module 21 are abutted and adhered on the substrate 12 for the device with the pressure-sensitive adhesive 25.
