Abstract: A LCD device prevents the color irregularities (e.g., the red-color irregularity) from occurring without complicating the fabrication processes of a color filter. Switching elements are formed on a first substrate. A color layer is formed on a second substrate. The color layer has a red sublayer, a green sublayer, and a blue sublayer. A liquid-crystal layer is located between the first and second substrates The second substrate includes no electrodes formed in such a way as to be located on a side nearer to the liquid-crystal layer with respect to the color layer. A green-coloring composition forming the green sublayer contains a pigment having a copper phthalocyanine skeleton. A ratio in weight of the pigment with respect to the green-coloring composition is equal to or less than approximately 27%.
