The reflective layer is not limited to this embodiment. Each of the button units 1 further includes a wavelength conversion material 4, and the wavelength conversion material 4 is disposed on the light path between the light guide plate 33 and the font pattern 131 (shown by the arrow direction in FIG. 2). The wavelength conversion material 4 is disposed on the upper surface of the light guide plate 33 as a light transmissive colored lacquer layer, and the light emitted from the zigzag pattern 131 is rendered in a predetermined color by the wavelength conversion material 4. For example, if the wavelength converting material 4 is a blue lacquer layer, the corresponding glyph pattern 131 may appear blue; if the wavelength converting material 4 is a yellow lacquer layer, the corresponding glyph pattern 131 may appear yellow. The wavelength converting material 4 of each button unit 1 can be selected according to requirements, such that the light that emits the glyph t 131 exhibits the same color as the wavelength converting material 4, whereby the keyboard device is composed of different button units i. The light emitted by the glyph pattern 131 can be presented in a plurality of colors and can be set according to the function of each button unit 1 and the color of the button unit 1 can be set to the same color. Color, the group of button units 1 can be distinguished by color, so that the user can quickly find the position of the desired button unit 丨. In the non-destructive example, each button unit 丨 further includes a support mechanism (not shown) provided on the bottom plate 2 for supporting the light-transmitting keycap 11 and a circuit unit (not shown) for generating a signal.
