ABSTRACT:
A liquid crystal display (LCD) panel and inspection method thereof. The LCD panel includes a first substrate having a reflective material layer formed on a first side of the first substrate; a second substrate having a black matrix formed on a first side of the second substrate, the first side of the second substrate face on to the first side of the first substrate; and a liquid crystal layer sandwiched between the first substrate and the second substrate; wherein the second substrate has at least one inspection area allowing light to pass to the first side of the first substrate. The inspection method includes: passing light through the inspection area to the first side of the first substrate; and inspecting cell process parameters of the LCD panel through light reflected from the first side of the first substrate.
