LIGHT EMITTING KEYPAD

摘要

A light emitting keypad is provided to prevent depression from being formed as light emitted from an EL(Electro Luminescence) device is reflected and interfered by having penetrating protrusions as necessary and allow light to be transmitted as it is, and facilitate assembling. A key plate(11) includes plural keys and through-holes. A rear surface layer(13) is positioned at a lower side of the key plate(11) and includes penetrating protrusions(14) that penetrate through the through-holes. A protection layer(20) is positioned at a lower side of the rear surface layer(13) and includes upper protrusions(21) corresponding to the keys. An EL device(30) is formed at lower side of the protection layer(20). The protection layer(20) is bonded with the EL device(30) in order to prevent infiltration of moisture or oxygen into the EL device(30).
