Abstract
A luminous keyboard includes plural keys, a membrane switch circuit member, a supporting plate and a backlight module. The membrane switch circuit member is located under the plural keys, and includes an upper wiring plate, a lower wiring plate and a separation plate. The supporting plate is located under the membrane switch circuit member and connected with the plural keys. The backlight module is located under the supporting plate to generate a light beam. A periphery region of at least one of the upper wiring plate, the lower wiring plate and the separation plate is bent to cover the supporting plate and the backlight module. Consequently, the light beam is not leaked out through the periphery region of the backlight module.
