Abstract: A liquid crystal display device includes a first substrate including a thin film transistor, a data line, a pixel electrode, and a common electrode, a second substrate, and liquid crystal sandwiched between the first and second substrates, wherein an image signal is applied to the thin film transistor through the data line to generate an electric field between the pixel electrode receiving the image signal and the common electrode such that the liquid crystal is rotated by the electric field in a plane which is in parallel with the first substrate. The first substrate includes an electrically insulating inorganic film covering the data line therewith, a first island-shaped electrically insulating organic film formed on the electrically insulating inorganic film above the data line, and a shield common electrode covering the first island-shaped electrically insulating organic film therewith and overlapping the data line when viewed vertically.

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%.

Abstract: A liquid-crystal display (LCD) device improves the performance of preventing the elution of impurity contained in the light-shielding layer (and the color layer) of the monochrome or color filter into the liquid crystal, thereby preventing defective operations of the LCD device (e.g., displaying defect) caused by impurity existing in the liquid crystal. The LCD device includes the protection layer made of a transparent organic resin, which satisfies at least one of a condition (a) that the transparent organic resin has a cross-link density of 70% or greater, and a condition (b) that the transparent organic resin has a Vickers hardness of 50 kgf/mm2 or greater. Preferably, an amount of internal impurity of the filter is 3 ng/cm2 or less. It is preferred that at least one selected from the group consisting of an acrylic resin, a styrene resin, and a polyimide resin is used as a base or matrix material of the transparent organic resin.
