Abstract:
1. A liquid crystal display panel, comprising: a black matrix formed of an organic resin material, at a predetermined region of a first substrate and at a boundary region of pixels; a color filter on the black matrix corresponding to the pixels; an over-coat layer formed of an organic material on the first substrate having the black matrix and the color filter; a seal pattern on the over-coat layer, the seal pattern including a support member and is entirely overlapped with the black matrix, the support member including a glass ball or glass fiber; a second substrate having a thin film transistor, the second substrate being attached to the first substrate by the seal pattern; and a spacer between the first and second substrates to maintain uniformly a cell gap, wherein a thickness(t) of the over-coat layer is 3 μm<t<5 μm, said thickness on the first substrate absorbing an external force, to prevent the compression or depression of the black matrix and the glass ball or glass fiber having a diameter of about ±1 μm compared to the cell gap between the first and second substrates, wherein the black matrix is extended to an end portion of the first substrate so that the side surface of black matrix is exposed to the outside of the attached first and second substrates.
