Abstract
Provided is a liquid crystal display device. The liquid crystal display device includes: an array substrate in which a pixel region is disposed, the pixel region including a thin film transistor and a pixel electrode connected to the thin film transistor; a counter substrate facing the array substrate; a liquid crystal layer interposed between the array substrate and the counter substrate; and a gap column spacer which maintains a cell gap between the array substrate and the counter substrate, and includes a bottom end portion having a first width, and a top end portion having a second width smaller than the first width.
Claims26
A liquid crystal display device, comprising:
- an array substrate in which a pixel region is disposed, the pixel region including a transistor and a pixel electrode connected to the transistor;
- a counter substrate facing the array substrate;
- a liquid crystal layer interposed between the array substrate and the counter substrate;
- and
- a gap column spacer which maintains a cell gap between the array substrate and the counter substrate, and includes a bottom end portion having a first width, and a top end portion having a second width smaller than the first width.
A method of manufacturing a liquid crystal display device, the method comprising:
- placing a photomask on a first substrate on which a photosensitive material is formed and conducting a light exposure, the photomask including a mask pattern which includes a full-tone pattern portion, a first half-tone pattern portion surrounding the full-tone pattern portion, and a light blocking pattern portion between the full-tone pattern portion and the first half-tone pattern portion;
- developing a photosensitive material to form a gap column spacer corresponding to the mask pattern;
- and
- combining a first substrate on which the gap column spacer is formed and a second substrate which faces the first substrate with a liquid crystal layer formed between the first substrate and the second substrate.
A liquid crystal display device, comprising:
- a gap column spacer and a press column spacer on a first substrate, the press column spacer having a thickness smaller than a thickness of the gap column spacer;
- and
- a second substrate facing the first substrate with a liquid crystal layer between the first substrate and the second substrate,
- wherein each of the gap column spacer and the press column spacer has a shape with a bottom end portion having a width greater than a top end portion, and
- wherein a ratio of a second width of the top end portion of the gap column spacer to a first width of the bottom end portion of the gap column spacer is smaller than a ratio of a fourth width of the top end portion of the press column spacer to a third width of the bottom end portion of the press column spacer.
