A half-tone liquid crystal display panel having half-tone pixels (50), each comprising a plurality of sub-pixels including first (31) and second (33) sub-pixels. Activation voltage is supplied to the first sub-pixel (31) from a TFT switch (18) and to the second sub-pixel (33) from the TFT switch through a coupling capacitor (39, 42). The second sub-pixel includes a storage capacitor (51, 53). Sensitivity of the activation voltage applied to the second sub-pixel resulting from capacitance non-uniformity across the panel is reduced by forming the coupling capacitor (39, 42) and the storage capacitor (51, 53) of the second sub-pixel with the same depositions utilizing a common dielectric layer (41). The capacitance (53) of the storage capacitor of the second sub-pixel is designed large compared to the capacitance (36) of the second sub-pixel. |
