PURPOSE:To facilitate the setting of the normal range and the excessive range for various measured values by indicating the value in one color within the normal range while in another color when it exceeds the preset reference level. CONSTITUTION:A laminated liquid crystal indication panel comprises a first liquid crystal display panel 1 and second liquid crystal display panel 2. Numerals 3, 4 and 5 indicate transparent glass substrates respectively which are fixed with a spacer at a space of about 10mum. First and second liquid crystal layers fill between the substrates 3 and 4 and the substrates 4 and 5 and have a nematic liquid of a negative dielectric anisotropy mixed with a dichroic dye. With such an arrangement, the level indication range (A) is indicated in blue, the level indication range (B) in red and the range (C) in white thereby facilitating the setting of the normal range and the excessive range for various measured values. |
