Abstract

An object of the present invention is to propose the structure and constitution of a liquid crystal display device having a protection plate, which prevents exfoliation of black painting at ends of the protection plate when dust on the protection plate of the liquid crystal display device is wiped off, thus preventing degradation of design features. The liquid crystal display device comprises: a transparent protection plate formed above a liquid crystal panel; a pair of polarizing plates disposed to sandwich and hold the liquid crystal panel; a transparent organic medium layer formed between the protection plate and the liquid crystal panel; a black coloring layer formed at ends of four sides on a side of the protection plate, the side being opposite to a side at which the transparent organic medium layer is disposed; and an anti-glare film composed of an anti-glare layer and an adhesion layer formed on a side of the protection plate, the side being opposite to a side at which the transparent organic medium layer is disposed.
