The display panel includes a first substrate; a second substrate; a shielding layer; a first color filter; and a spacer. The second substrate is disposed opposite the first substrate. The shielding layer is disposed over the second substrate, wherein the shielding layer includes two shielding pattern rows projected onto the second substrate. The first color filter is disposed over the second substrate and the shielding layer. The spacer is disposed over the first color filter, wherein the spacer includes a spacer pattern projected onto the second substrate, and the spacer pattern overlaps one of the two shielding pattern rows, and the one of the two shielding pattern rows includes an expansion portion, wherein the expansion portion has an edge and at least part of the edge is curved. ## Claims ### Claim 1 A display panel, comprising: a first substrate; a second substrate disposed opposite the first substrate; a shielding layer disposed over the second substrate, wherein the shielding layer comprises two shielding pattern rows projected onto the second substrate; a first color filter disposed over the second substrate and the shielding layer; and a spacer disposed over the first color filter, wherein the spacer comprises a spacer pattern projected onto the second substrate, and the spacer pattern overlaps one of the two shielding pattern rows, and the one of the two shielding pattern rows comprises an expansion portion, wherein the expansion portion has an edge and at least part of the edge is curved. ### Claim 2 (depends on 1) The display panel as claimed in claim 1, further comprising: a second color filter and a third color filter disposed at opposite sides of the first color filter respectively, wherein the first color filter overlaps the second color filter, whereas the first color filter does not overlap the third color filter. ### Claim 3 (depends on 2) The display panel as claimed in claim 2, wherein the spacer is a main spacer and the display panel further comprises a sub-spacer overlapping the third color filter. ### Claim 4 (depends on 3) The display panel as claimed in claim 3, wherein the sub-spacer overlaps the one of the two shielding pattern rows. ### Claim 5 (depends on 1) The display panel as claimed in claim 1, further comprising: a planarization layer disposed over the first color filter, wherein the spacer is disposed over the planarization layer. ### Claim 6 (depends on 1) The display panel as claimed in claim 1, wherein the first substrate comprises a data line disposed over the second substrate. ### Claim 7 (depends on 6) The display panel as claimed in claim 6, wherein the first color filter extends along the data line. ### Claim 8 (depends on 1) The display panel as claimed in claim 1, wherein a portion of a side of the first color filter is curved. ### Claim 9 (depends on 1) The display panel as claimed in claim 1, wherein the spacer is a main spacer, and the display panel further comprises: a sub-spacer disposed between the first color filter and the third color filter, wherein the main spacer has a first height, and the sub-spacer has a second height, wherein the first height is greater than the second height. ### Claim 10 A display device, comprising: a first substrate; a second substrate disposed opposite the first substrate; a shielding layer disposed over the second substrate, wherein the shielding layer comprises two shielding pattern rows projected onto the second substrate; a first color filter disposed over the second substrate; a spacer disposed over the first color filter, wherein the spacer is a main spacer and comprises a spacer pattern projected onto the second substrate, and the spacer pattern overlaps one of the two shielding pattern rows, and the one of the two shielding pattern rows comprises an expansion portion, wherein the expansion portion has an edge and at least part of the edge is curved; and a sub-spacer disposed over the second substrate. ### Claim 11 (depends on 10) The display device as claimed in claim 10, further comprising: a second color filter and a third color filter disposed at opposite sides of the first color filter respectively, wherein the first color filter overlaps the second color filter, whereas the first color filter does not overlap the third color filter. ### Claim 12 (depends on 11) The display device as claimed in claim 11, wherein the sub-spacer overlaps the third color filter. ### Claim 13 (depends on 11) The display device as claimed in claim 11, wherein the sub-spacer is disposed between the first color filter and the third color filter, wherein the main spacer has a first height, and the sub-spacer has a second height, wherein the first height is greater than the second height. ### Claim 14 (depends on 10) The display device as claimed in claim 10, wherein the sub-spacer overlaps the one of the two shielding pattern rows. ### Claim 15 (depends on 10) The display device as claimed in claim 10, further comprising: a planarization layer disposed over the first color filter, wherein the spacer is disposed over the planarization layer. ### Claim 16 (depends on 10) The display device as claimed in claim 10, wherein the first substrate comprises a data line disposed over the second substrate. ### Claim 17 (depends on 16) The display device as claimed in claim 16, wherein the first color filter extends along the data line. ### Claim 18 (depends on 11) The display device as claimed in claim 11, wherein a portion of a side of the first color filter is curved.
