Abstract: A super-slim touch keyboard and a super-slim smart cover device including the same are provided. The super-slim touch keyboard includes a lower case, a touch circuit board including a key pattern disposed on the lower case and a touch wheel pattern disposed adjacent to the key pattern, a piezoelectric sensor film layer formed on the touch circuit board and including a piezoelectric sensor printed on a portion thereof corresponding to the key pattern, an electro-luminance (EL) film layer formed on the piezoelectric sensor film layer, a keypad layer formed on the EL film layer and including a plurality of keys at a portion thereof corresponding to the key pattern, and an upper case disposed to be coupled to the lower case at a periphery of the keypad layer and including a touch wheel at a portion thereof corresponding to the touch wheel pattern.
