Abstract
A liquid crystal display is provided, which includes: a substrate; a color filter formed on the substrate, and having a depression and an opening; a common electrode formed on the color filter, and having a depression; and a black member formed on the common electrode and located at the depressions of the common electrode.
Claims17
A liquid crystal display, comprising:
- a first substrate;
- a plurality of gate lines on the first substrate;
- a plurality of data lines extending across the gate lines;
- a plurality of pixels defined by the gate lines and the data lines;
- a second substrate;
- a color filter including a depression, formed on the second substrate, corresponding to each pixel;
- a common electrode formed on the color filter;
- a light blocking member, disposed between the pixels, formed on the common electrode;
- and
- a protrusion formed on the common electrode located at the depression of the color filter;
- wherein the protrusion is made of the same material as the light blocking member.

6 more elements
A method for manufacturing a liquid crystal display panel, comprising:
- forming a color filter having a depression and an opening;
- forming a common electrode on the color filter;
- and
- forming a light blocking member on the common electrode,
- wherein the light blocking member is formed by a photolithography process using a photo-mask having an opaque area facing the depression of the color filter, a translucent area facing the opening of the color filter, and a transmissive area facing a portion of the color filter that does not include the depression or the opening.
2 more elements
A liquid crystal display, comprising:
- a substrate;
- a color filter, provided on the substrate, having a depression and an opening;
- a common electrode, provided on the color filter, having a depression formed by the depression of the color filter, and having a first surface and a second surface located father from the substrate than the first surface;
- a black matrix formed on the common electrode and contacting the second surface of the common electrode;
- and
- a protrusion formed on the common electrode located at the depression of the color filter, wherein the protrusion is made of the same material as the black matrix.
