Abstract
A manufacturing method of an LCD includes forming an align key including metal on a first substrate, coating a light blocking layer overlapping the align key, transmitting an infrared ray thought the light blocking layer on the align key, recognizing the align key by the transmitting the infrared ray to align key and the light blocking layer, and forming a light blocking member by exposing and developing the light blocking layer.
Claims14
A manufacturing method of a liquid crystal display (“LCD”), the method comprising:
- forming an align key including metal on a substrate;
- coating a light blocking layer overlapping the align key;
- transmitting an infrared ray thought the light blocking layer on the align key;
- recognizing the align key by transmitting the infrared ray to the align key and the light blocking layer;
- and
- forming a light blocking member by exposing and developing the light blocking layer.
A manufacturing method of a liquid crystal display (“LCD”), the method comprising:
- forming the light blocking layer including carbon black at less than about 7 wt % on a first substrate.
A liquid crystal device (“LCD”) comprising:
- a substrate;
- and
- a light blocking member,
- wherein the light blocking member has infrared ray transmittance of greater than about 60% and optical density of greater than about 3.0.
