Abstract

An embodiment of the present invention discloses a liquid crystal display panel, including: first substrate; a main spacer and a sub-spacer, both disposed on the first substrate, a height of the main spacer is higher than a height of the sub-spacer; wherein an identification tag, disposed adjacent to one of the main spacer and the sub-spacer configured to identify the primary and sub-spacers. An embodiment of the present invention also discloses a liquid crystal display device. With the present invention, there are advantages of easy identification of the main spacer and the sub-spacer.

Claims (24)

1. A liquid crystal display panel, comprising:

a first substrate;

a main spacer and a sub-spacer, both disposed on the first substrate, a height of the main spacer is higher than a height of the sub-spacer; and

an identification tag, disposed adjacent to one of the main spacer and the sub-spacer configured to identify the main spacer and the sub-spacer,

wherein a black matrix is disposed on the first substrate, the main spacer and the sub-spacer are both disposed on the black matrix, and the black matrix is integrally formed with the main spacer and the sub-spacer,

wherein the identification tag is an identification hole formed by hollowing out a portion of the black matrix,

wherein a metal layer is under the identification hole, and the metal layer is opaque, and

wherein a dimension of the identification hole in the lengthwise direction is smaller than a dimension of the metal layer in the lengthwise direction, and a dimension of the identification hole in the widthwise direction is smaller than a dimension of the metal layer in the widthwise direction.

2. The liquid crystal display panel according to claim 1 , wherein the metal layer is a data line or a scan line.

3. The liquid crystal display panel according to claim 1 , wherein a dimension of the identification hole in the lengthwise direction is greater than or equal to 10 μm and a dimension of it in the widthwise direction is greater than or equal to 10 μm.

6. The liquid crystal display panel according to claim 1 , wherein a difference between sizes of projections of the main spacer and the sub-spacer on a horizontal plane is less than 10%.

7. A liquid crystal display device comprises a liquid crystal display panel, which comprises:

a first substrate;

a main spacer and a sub-spacer, both disposed on the first substrate, a height of the main spacer is higher than a height of the sub-spacer; and

an identification tag, disposed adjacent to one of the main spacer and the sub-spacer configured to identify the main spacer and the sub-spacer,

wherein a black matrix is disposed on the first substrate, the main spacer and the sub-spacer are both disposed on the black matrix, the black matrix is integrally formed with the main spacer and the sub-spacer,

wherein the identification tag is an identification hole formed by hollowing out a portion of the black matrix,

wherein a metal layer is under the identification hole, and the metal layer is opaque, and

wherein a dimension of the identification hole in the lengthwise direction is smaller than a dimension of the metal layer in the lengthwise direction, and a dimension of the identification hole in the widthwise direction is smaller than a dimension of the metal layer in the widthwise direction.

8. The liquid crystal display device according to claim 7 , wherein the metal layer is a data line or a scan line.

9. The liquid crystal display device according to claim 7 , wherein a dimension of the identification hole in the lengthwise direction is greater than or equal to 10 μm and a dimension of it in the widthwise direction is greater than or equal to 10 μm.
