A liquid crystal display panel and a liquid crystal display (LCD) device are discussed. One monochromatic light is transmitted through a liquid crystal layer and converted into white light having a plurality of wavelengths through upper photo conversion layer, thus improving light transmittance of liquid crystal and reducing a change in a screen color. The liquid crystal display panel includes: first substrate over the backlight unit; a liquid crystal layer over the first substrate to transmit the one monochromatic light; a photo conversion layer over the liquid crystal layer for converting the one monochromatic light into white light; a color filter layer over the photo conversion layer for filtering the converted white light to display color; and a second substrate on the color filter layer.

A transparent liquid crystal display device includes: first and second substrates facing and spaced apart from each other; a polarizing plate over an outer surface of the first substrate; first and second electrodes and a passivation layer between the first and second electrodes over an inner surface of the first substrate, the first electrode having a plate shape, the second electrode having a shape of bars; a third electrode over an inner surface of the second substrate; at least one color filter over an outer surface of the second substrate, the at least one color filter including a colored dichroic dye material; and a liquid crystal layer between the first and second substrate, the liquid crystal layer including a liquid crystal material and a black dichroic dye material.
