Abstract
A liquid crystal display (LCD) apparatus is provided. The LCD apparatus includes a first substrate and a second substrate, each including a display area and a non-display area, a sealant disposed between the non-display area of the first substrate and the non-display area of the second substrate, and a first contact area and a light shielding pattern that are disposed in the non-display area of the first substrate. The light shielding pattern is disposed on one outermost side of the first substrate, the first contact area is disposed between the light shielding pattern and the display area, and the sealant contacts the first substrate in the first contact area.
Claims18
A liquid crystal display (LCD) apparatus comprising:
- a first substrate and a second substrate, each including a display area and a non-display area;
- a sealant disposed between the non-display area of the first substrate and the non-display area of the second substrate;
- a first contact area and a light shielding pattern that are disposed in the non-display area of the first substrate, and
- an organic insulation layer in the non-display area of the second substrate;
- and
- a second contact area and an inorganic insulation layer in the non-display area of the second substrate,
- wherein a portion of the sealant is in the second contact area,
- wherein
- the light shielding pattern and the organic insulation layer are respectively on one outermost side of the first substrate and the second substrate to overlap with each other, being configured to facilitate a scribing process,
- the first contact area is disposed between the light shielding pattern and the display area, and
- the sealant is adjacent to the light shielding pattern on the first substrate and the organic insulation layer on the second substrate,
- wherein the sealant is in a line with the light shielding pattern and the organic insulation layer in the one outermost side of the first substrate and the second substrate, and
- wherein the organic insulation layer is not formed at the second contact area, and the portion of the sealant in the second contact area contacts the inorganic insulation layer.
A liquid crystal display (LCD) apparatus comprising:
- an upper substrate having an inner surface at which a light shielding layer, a color filter structure, and an overcoat layer are provided;
- a lower substrate having an inner surface at which a thin-film transistor (TFT) array, a pixel electrode, a common electrode, and a planarization layer are provided, wherein the planarization layer includes organic insulation material;
- and
- a sealing region along a periphery of the upper and lower substrates having their inner surfaces facing each other and adhesively attached together by a sealant in the sealing region,
- the sealing region having an open area configured to allow adhesive attachment between the sealant and the upper and lower substrates, and having a scribing area, which is adjacent to the open area along an edge of the periphery, configured to facilitate an LCD cell separation process using laser scribing, wherein the planarization layer is located in the scribing area but not in the open area, and
- the sealing region allowing the sealant to have minimal overall width to achieve a narrower bezel area when compared to an LCD apparatus without the sealing region,
- wherein the sealant is in a line with the light shielding pattern and the planarization layer in an outermost side of the upper substrate and the lower substrate, and
- wherein the sealant at the open area contacts an inorganic insulation layer.
