A liquid crystal display for preventing a light leakage is discussed. According to an embodiment, the liquid crystal display panel includes a first substrate having a black matrix that defines a non-display region and a display region, a second substrate on which a pixel array is formed, a liquid crystal layer between the first substrate and the second substrate, and a sealant between the first substrate and the second substrate, wherein a distance between the sealant and the black matrix is different in accordance with a position on which the sealant is formed.

The present disclosure relates to a wide viewing angle liquid crystal display device working in normally white mode. An wide viewing angle IPS mode TFT-LCD operating in a normally white mode comprises a first polarizer having a first polarizing axis parallel to a first direction; a second polarizer having a second polarizing axis parallel to the first direction; and liquid crystal molecules disposed between the first polarizer and the second polarizer, and having an initial alignment direction parallel to the first direction. The wide view angle IPS mode TFT-LCD according to the present disclosure is a operating in normally white mode which represents full white gray-scale without yellowish phenomenon, and does not need any additional optical film for overcoming the yellowish phenomenon so that the manufacturing process is simply and cost is lower than the LCD according to the related art.
