Abstract
The present invention discloses a liquid crystal display (LCD) device and a method of fabricating the same that can be used in a large size with a TN or an AFLC. More specifically, a liquid crystal display includes first and second substrates, a light-transmitting portion in the first and second substrates, wherein the light-transmitting portion has a first cell gap, a light-shielding portion in the first and second substrates, wherein the light-shielding portion has a second cell gap, wherein the second cell gap is larger than the first cell gap, and a liquid crystal layer between the first and second substrates.
Claims21
A liquid crystal display comprising:
- a first substrate having a first protective layer and a pixel electrode;
- a second substrate having a common electrode;
- a light-transmitting portion in the first and second substrates, wherein the light-transmitting portion has a first cell gap between the pixel electrode and the common electrode;
- a light-shielding portion in the first and second substrates, wherein the light-shielding portion has a second cell gap between a recessed portion of the common electrode and a recessed portion of the first protective layer exposing a portion of a gate insulating layer, wherein the second cell gap is larger than the first cell gap;
- a black matrix on the second substrate;
- a color filter layer on the black matrix;
- and
- a liquid crystal layer between the first and second substrates.
A liquid crystal display comprising:
- a first substrate having gate and data lines and a protection layer and a second substrate, the first and second substrates defining a first cell gap therebetween;
- a first hole in the protection layer of the first substrate, the first hole corresponding to the gate and data lines and exposing a portion of a gate insulating layer;
- a second hole in the second substrate, wherein the first and second holes broaden the first cell gap to form a second cell gap;
- a black matrix on the second substrate;
- a color filter layer on the black matrix;
- and
- a liquid crystal layer between the first and second substrates.
A method of fabricating a liquid crystal display having first and second substrates, the method comprising the steps of:
- forming a first protective layer and a pixel electrode on the first substrate;
- forming a common electrode on the second substrate;
- forming a light-transmitting portion in the first and second substrates, wherein the light-transmitting portion has a first cell gap between the pixel electrode and the common electrode;
- forming a light-shielding portion in the first and second substrates, wherein the light-shielding portion has a second cell gap between a recessed portion of the common electrode and a recessed portion of the first protective layer to expose a portion of a gate insulating layer, wherein the second cell gap is larger than the first cell gap;
- forming a black matrix on the second substrate;
- forming a color filter layer on the black matrix;
- and
- forming a liquid crystal layer between the first and second substrates.
