The display panel includes a display area AA, a first non-display area B1, and at least one device arrangement area Q, the first non-display area B1 surrounding the display area AA, and the first non-display area B1 surrounding at least a portion of the device arrangement area Q; a first substrate 10 and a second substrate 20 which are oppositely arranged, and a liquid crystal layer LC and a spacer 30 which are arranged between the first substrate 10 and the second substrate 20, wherein the spacer 30 comprises a plurality of first spacers 31; the first substrate 10 is provided with a black matrix 40 and a plurality of color resistance units 50 arranged in a matrix, the black matrix 40 comprises a plurality of first shading parts 43, a plurality of first shading strips 41 extending along a row direction and a plurality of second shading strips 42 extending along a column direction, and the row direction and the column direction are intersected; the first shading part 43 is positioned at the intersection of the first shading strip 41 and the second shading strip 42, and the orthographic projection of the first spacer 31 on the plane of the first substrate 10 is positioned in the orthographic projection of the first shading part 43 on the plane of the first substrate 10; the display area AA includes a first display area a11 adjacent to the device arrangement area Q; in the first display region a11, the first light shielding portion 43 has an increasing area of orthographic projection on the plane of the first substrate 10 in a direction in which the first display region a11 points toward the device arrangement region Q.

Note that the first non-display region B1 surrounds at least a part of the device disposition region Q, and as shown in fig. 1, a partial region of the first non-display region B1 is adjacent to the device disposition region Q and the partial non-display region has a U shape, and the device disposition region Q is located in the U-shaped region.

It is understood that, in the actual manufacturing process, the first light-shielding portions 43, the first light-shielding tapes 41 and the second light-shielding tapes 42 are made of the same material and are manufactured in the same process as a whole. In the present application, it is merely for convenience of describing the black matrix 40 at different positions, and there is no essential difference.

In the present invention, the first light-shielding portion 43 is located at the intersection of the first light-shielding tape 41 and the second light-shielding tape 42; the width of the first light-shielding portions 43 is larger than the width of the second light-shielding tapes 42 in the row direction; the width of the first light-shielding portions 43 is larger than the width of the first light-shielding tapes 41 in the column direction. In fig. 3, only the first light-shielding portion 43 is illustrated as a circle, but the first light-shielding portion 43 may be a diamond, a square, an oval, a triangle, a parallelogram, or the like, and may be designed according to actual requirements, and the present invention is not limited thereto.

In addition, in this embodiment, only one color resistance unit 50 includes three color resistance blocks, the first display area a11 includes 6 rows × 6 columns of color resistance blocks, and the first spacer 31 is disposed every other three color resistance blocks in the row direction and every other two color resistance blocks in the column direction, the number of color resistance blocks specifically included in each color resistance unit, the size of the first display area a11, and the disposition density of the first spacer 31 may be designed according to actual requirements, which is not limited by the invention.

In the display panel provided by the invention, the first light shielding part 43 is arranged, so that the orthographic projection of the first spacer 31 on the plane of the first substrate 10 is positioned in the orthographic projection of the first light shielding part 43 on the plane of the first substrate 10. In the first display area a11, along the direction in which the first display area a11 points to the device installation area Q, the orthographic projection area of the first light shielding portions 43 on the plane of the first substrate 10 gradually increases, that is, in the first display area AA1, the closer to the device installation area Q, the larger the orthographic projection area of the first light shielding portions 43 on the plane of the first substrate 10. Therefore, when the vicinity of the device arrangement region Q is pressed, a larger relative displacement between the first substrate 10 and the second substrate 20 can occur without light leakage around the first spacer 31. Therefore, the light leakage resistance of the first display area a11 near the device-disposing area Q is enhanced, and the display effect of the product and the visual experience of the user are improved.

Note that, in the above-described embodiment, only the case where the first display region a11 is located on the lower side of the device arrangement region Q is described as an example. In practical design, as shown in fig. 4, fig. 4 is a schematic plan view of another display panel provided in the embodiment of the present invention, and the display panel may further include one or more of a first display region a12 (located at the left side of the device installation region Q), a first display region a13 (located at the right side of the device installation region Q), a first display region a14 (located at the lower side of the device installation region Q), a first display region a15 (located at the lower right side of the device installation region Q), and the like. The specific position of the first display area may be designed according to actual requirements, which is not limited in the present invention.

In some alternative embodiments, referring to fig. 1-3 and 5, fig. 5 is a partial enlarged view of area QA in fig. 3, and in subsequent figures, like structures have been given like reference numerals and are not described in detail. The orthographic projection of the first spacer 31 on the plane of the first substrate 10 is a first projection, the orthographic projection of the first light shielding part 43 on the plane of the first substrate 10 is a second projection, and the minimum distances of the edge of the first projection and the edge of the second projection in all directions are equal.

In the present embodiment, only the orthographic projections of the first spacer 31 and the first light blocking cloth 43 are circular. The actual application can be set according to specific situations, and the invention is not limited to this. In the directions shown by the arrows in fig. 5, the minimum distances between the edge of the first projection and the edge of the second projection in the respective directions are equal, that is, the first projection and the second projection are two concentric circles. As described above, in the first display region a11, the area of the orthographic projection of the first light shielding portions 43 on the plane of the first substrate 10 gradually increases in the direction in which the first display region a11 points toward the device installation region Q, and therefore, in the present embodiment, the size of the first spacers 31 is adjusted in the direction in which the first display region a11 points toward the device installation region Q, so that the area of the orthographic projection of the first spacers 31 on the plane of the first substrate 10 gradually increases, and the minimum distances in each direction between the edge of the first projection of different first spacers 31 and the edge of the second projection of the corresponding first light shielding portion 43 can be made equal to each other.

In the embodiment, the minimum distances of the edge of the first projection and the edge of the second projection in all directions are equal, so that the phenomenon of light leakage of the display panel can be effectively avoided; meanwhile, the size of the first spacer 31 is adjusted to gradually increase the orthographic projection area of the first spacer on the plane where the first substrate 10 is located, so that the first spacer 31 in the first display area can provide enough supporting force, thereby increasing the pressure resistance of the display panel.

In some alternative embodiments, referring to fig. 1, fig. 2 and fig. 6, fig. 6 is a schematic plan view of another first substrate provided in an embodiment of the present invention. The orthographic projection areas of the first spacers 31 on the plane of the first substrate 10 are all equal.

In this embodiment, all the first spacers 31 have the same orthographic projection area on the plane of the first substrate 10, and since the orthographic projection area of the first light-shielding portions 43 on the plane of the first substrate 10 is gradually increased in the first display area a11 along the direction in which the first display area a11 points to the device placement area Q, the distance between the orthographic projection edge of the first spacer 31 and the orthographic projection edge of the corresponding first light-shielding portion 43 is gradually increased along the direction in which the first display area a11 points to the device placement area Q. That is, the closer to the device installation region Q, the larger the area of the first light shielding portion 43 not occupied by the orthographic projection of the first spacer 31 on the plane of the first substrate 10 is, so that the light leakage or poor display of the display panel can be effectively avoided.

In some alternative embodiments, referring to fig. 1, 2, 7 and 8, fig. 7 is a schematic plan view of a first substrate provided by an embodiment of the present invention, and fig. 8 is a partially enlarged view of a region QB in fig. 7. An orthographic projection of the first spacer 31 on the plane of the first substrate 10 is a first projection, an orthographic projection of the first light shielding part 43 on the plane of the first substrate 10 is a second projection, a minimum distance between an edge of the first projection and an edge of the second projection on a side away from the device installation area Q is a first distance e1, and a minimum distance between an edge of the first projection and an edge of the second projection on a side close to the device installation area Q is a second distance d 1; in the first display region a11, the first distance e1 gradually increases and the second distances d1 are all equal in a direction in which the first display region a11 points to the device arrangement region Q.

In the present invention, only the first display area a11 including 6 rows × 6 columns of color resist blocks and three first spacers 31 arranged in the column direction will be described as an example. Taking the first spacer 311 as an example, referring to fig. 8, the minimum distance between the edge of the first projection and the edge of the second projection on the side far from or close to the device installation area Q is, specifically, the minimum distance between the edge of the first projection and the edge of the second projection on the side far from or close to the device installation area Q is determined by taking a straight line m which is perpendicular to the direction in which the first display area a11 points to the device installation area Q and is the geometric center of the first projection as a boundary (for example, in fig. 8, the direction in which the first display area a11 points to the device installation area Q is the column direction, and the first projection is a circle, and then the straight line m which is perpendicular to the column direction and is the center of the first projection is the boundary). The distance between the edge of the first projection and the edge of the second projection close to one side of the device setting area Q is the distance between the projections of the edge of the first projection and the edge of the second projection on one side of the straight line m close to the setting area Q; the distance between the edge of the first projection and the edge of the second projection on the side far away from the device setting area Q is the distance between the projections of the edge of the first projection and the edge of the second projection on the side far away from the device setting area Q and also includes the distance between the points of the edge of the first projection and the projection of the edge of the second projection on the straight line m on the side far away from the device setting area Q.

As shown in fig. 7 and 8, the geometric centers of the first projection and the second projection of the first spacer 311 do not overlap, and on the side of the straight line m away from the device installation region Q, the edge of the first projection and the edge of the second projection have a distance e1 (where the straight line where the line segment is located overlaps the straight line m), a distance e2, and a distance e3, where the distance e1 is the smallest, i.e., the first distance e 1. On the side of the straight line m near the device arrangement region Q, the edge of the first projection and the edge of the second projection have a distance d1 and a distance d2, wherein the distance d1 is the smallest, i.e., the second distance d 1. In the first display region a11, the first distance e1 gradually increases and the second distances d1 are all equal in a direction in which the first display region a11 points to the device arrangement region Q. With reference to fig. 7 and 8, a first spacer 313, a first spacer 312, and a first spacer 311 are respectively disposed in the column direction. In the column direction, the first distance (not shown) of the first spacer 313, the first distance (not shown) of the first spacer 312, the first distance (distance e1 in fig. 8) of the first spacer 311 gradually increase; the second distance (not shown) of the first spacer 313, the second distance (not shown) of the first spacer 312, and the second distance (distance d1 in fig. 8) of the first spacer 311 are gradually increased.

The inventors have studied and found that when the vicinity of the device mounting region Q is pressed, light leakage is more likely to occur in general at a side of the first spacer 31 away from the device mounting region Q due to the presence of stress. Therefore, in the present embodiment, the closer to the device disposition region Q, the larger the first distance between the edge of the first projection and the edge of the second projection is, so that when the vicinity of the device disposition region Q is pressed, the phenomenon of light leakage around the first spacer 31 does not occur.

In some alternative embodiments, referring to fig. 2, 4, and 9 to 12, fig. 9 is a schematic plan view of a first substrate according to an embodiment of the present invention, fig. 10 is a partially enlarged view of a region QC of fig. 9, fig. 11 is a partially enlarged view of a region QD of fig. 9, and fig. 12 is a partially enlarged view of a region QE of fig. 9. Fig. 9 only shows that the first display area a11, the first display area a12, and the first display area a14 adopt the technical solution provided by the present invention. The color resistance unit 50 includes a plurality of color resistance blocks 51; the plurality of color blocking blocks 51 adjacent to the first spacer 31 include a first color blocking block 511 and a second color blocking block 512, the first color blocking block 511 is located on one side of the first spacer 31 close to the device setting area Q, and the second color blocking block 512 is located on one side of the first spacer 31 far away from the device setting area Q; the color-blocking block 51 further includes a third color-blocking block 513, where the third color-blocking block 513 is adjacent to the second color-blocking block 512 and is located on a side of the second color-blocking block 512 away from the device setting area Q; in the first display area, along a direction in which the first display area points to the device setting area Q, a minimum distance between the first color block 511 and the second color block 512 is a third distance, a minimum distance between the second color block 512 and the third color block 513 is a fourth distance, and the third distance is greater than the fourth distance.

It should be noted that the first color block 511, the second color block 512, and the third color block 513 in the embodiment of the invention are merely divided according to the relative positional relationship with the first spacer 31a and the device setting region Q, and are not limited to the color block unit 50. It is understood that the third color block 513 corresponding to the first spacer 31a is also substantially equivalent to the first color block 511 corresponding to the first spacer 31 b. In addition, in the actual process, partial overlapping can occur in the orthographic projection of the color resistance blocks and the black matrix on the plane where the first substrate is located, and the minimum distance between the color resistance blocks in the application is actually the minimum distance between the opening areas corresponding to the color resistance blocks.

Specifically, in the first display area a11, in a direction in which the first display area a11 is directed to the device arrangement area Q, that is, in the column direction, the minimum width of the black matrix between the first color block 511 and the second color block 512 adjacent to the first spacer 31a is a third distance f1, and the minimum width of the black matrix between the second color block 512 and the third color block 513 is a third distance g 1.

The orthographic projection of the first spacer 31a on the plane of the first substrate is always positioned in the orthographic projection of the first shading part 43 on the plane of the first substrate, and the aperture ratio of the display panel is improved and the display effect is improved while the extrusion light leakage phenomenon is avoided by adjusting the position of the aperture area and the width of the black matrix.

Referring to fig. 9 and 11, the plurality of color blocking blocks 51 adjacent to the first spacer 31d include a first color blocking block 511 and a second color blocking block 512, the first color blocking block 511 is located at a side of the first spacer 31d close to the device setting area Q, and the second color blocking block 512 is located at a side of the first spacer 31d far from the device setting area Q; the color-blocking block 51 further includes a third color-blocking block 513, where the third color-blocking block 513 is adjacent to the second color-blocking block 512 and is located on a side of the second color-blocking block 512 away from the device setting area Q; in the first display area a12, along the direction in which the first display area a12 points to the device setting area Q, the minimum distance between the first color block 511 and the second color block 512 is a third distance f1, the minimum distance between the second color block 512 and the third color block 513 is a fourth distance g1, and the third distance f1 is greater than the fourth distance g 1.

That is, the position of the opening area corresponding to the second resist 512 is adjusted so as to be located on the side away from the device installation area Q. That is, the position of the opening area and the width of the black matrix are adjusted, so that the opening rate of the display panel is improved and the display effect is improved while the extrusion light leakage phenomenon is avoided.

In this embodiment, the opening area corresponding to the second color resist 512 is moved to the side away from the device mounting area Q, that is, both in the row direction and the column direction, the opening area is disposed to the side away from the device mounting area Q.
