The LCD module(200) indicates many colors and R, G, B lamps(81,82,83), which are used as a light source of the LCD module(200), are installed in order in a side of the light guiding board(70). These lamps(80) are wrapped by the reflection sheet(85) of the lamp. The optical sheets(30), which diffuse and condense the light emitted from R, G, B lamps(81,82,83), are piled up on the light guiding board(70). The LCD panel(40), which indicates the information according to the light emitted from R, G, B lamps(81,82,83) and the electric signal, is installed on the optical sheets(30).
