Abstract

Obtained is a liquid crystal display panel that allows for a continued check on whether a polarizing plate is affixed at an appropriate position while retaining the design flexibility. In a liquid crystal display panel ( 10 ), two recess portions (BMa 1 ) and two island portions (BMa 2 ) are provided on an edge of a black matrix (BM), and two recess portions ( 3 a ) and two recess portions ( 4 a ) are provided on respective edges of a rear polarizing plate ( 3 ) and a front polarizing plate ( 4 ) at positions that match the two recess portions (BMa 1 ) and the two island portions (BMa 2 ).

Claims (17)

1. A liquid crystal display panel, comprising:

a black matrix that blocks light between pixels disposed in a matrix in an image display portion; and

a pair of polarizing plates disposed on respective outer side surfaces of two substrates sandwiching the black matrix, wherein

at least two first shape portions are provided on an edge of the black matrix, the at least two first shape portions each being a shape that includes a recess portion recessed toward a center of the black matrix from the edge of the black matrix or a projection portion projecting outwardly from the center of the black matrix from the edge of the black matrix,

at least two second shape portions are provided in at least one of the pair of polarizing plates, the at least two second shape portions each being a shape that includes a recess portion recessed toward a center of the least one of the pair of polarizing plates from an edge of the at least one of the pair of polarizing plates or a projection portion projecting outwardly from the center of the at least one of the pair of polarizing plates from the edge of the at least one of the pair of the polarizing plates, and

as viewed in a plan view,

one of the at least two first shape portions and one of the at least two second shape portions are disposed at positions that match each other, and another one of the at least two first shape portions and another one of the at least two second shape portions are disposed at positions that match each other.

2. The liquid crystal display panel according to claim 1 , wherein the liquid crystal display panel is circular.

3. The liquid crystal display panel according to claim 1 , wherein the at least two first shape portions and the at least two second shape portions are disposed in a peripheral portion of the liquid crystal display panel, the peripheral portion being a region outside the image display portion.

4. The liquid crystal display panel according to claim 1 ,

wherein the at least two first shape portions are disposed symmetric about a center of the black matrix, and

wherein the at least two second shape portions are disposed symmetric about a center of the polarizing plate in which the at least two second shape portions are provided.

5. The liquid crystal display panel according to claim 1 ,

wherein the at least two first shape portions consist of two first shape portions,

wherein the at least two second shape portions consist of two second shape portions, and

wherein the two second shape portions are provided on the edge of each of the pair of polarizing plates.

6. A display apparatus, comprising: the liquid crystal display panel according to claim 1 .
