The outer surface comprises a first region and a second region beside the first region. An edge of the patterned light shielding layer at least partially overlaps a boundary between the first region and the second region. The patterned oxide layer is located within one of the first region and the second region while exposes the other of the first region and the second region. ## Claims ### Claim 1 A display panel having a first region and a second region beside the first region, the display panel comprising; a top substrate having an outer surface; a display layer covered by the top substrate; a patterned light shielding layer disposed on the outer surface of the top substrate and located within the first region, wherein an edge of the patterned light shielding layer at least partially overlaps a boundary between the first region and the second region; and a patterned oxide layer disposed on the outer surface of the top substrate and located within the first region while exposes the second region, wherein the outer surface of the top substrate is modified at the second region to form a modified outer surface, and the modified outer surface of the top substrate is more hydrophobic than the patterned oxide layer, wherein the patterned oxide layer is disposed between the top substrate and the patterned light shielding layer, wherein the patterned oxide layer has a modified surface with a hydrophobic property in contact with the patterned light shielding layer, and wherein the modified outer surface is more hydrophobic than the modified surface of the patterned oxide layer. ### Claim 2 (depends on 1) The display panel according to claim 1, wherein the outer surface of the top substrate is further modified at the first region, the modified outer surface is located at the second region and the first region, and the patterned oxide layer is disposed on the modified outer surface at the first region. ### Claim 3 (depends on 1) The display panel according to claim 1, further comprising an underlying oxide layer disposed on the outer surface of the top substrate and located at the second region. ### Claim 4 (depends on 3) The display panel according to claim 3, wherein the underlying oxide layer exposes the first region. ### Claim 5 (depends on 3) The display panel according to claim 3, wherein the underlying oxide layer further located at the first region and is disposed between the top substrate and the patterned oxide layer. ### Claim 6 (depends on 3) The display panel according to claim 3, wherein the underlying oxide layer has a modified surface with hydrophobic property. ### Claim 7 (depends on 3) The display panel according to claim 3, wherein a material of the patterned oxide layer is different from a material of the underlying oxide layer. ### Claim 8 (depends on 1) The display panel according to claim 1, wherein the outer surface of the top substrate is modified at the first region to form the modified outer surface and the patterned oxide layer is disposed on the modified outer surface. ### Claim 9 (depends on 1) The display panel according to claim 1, wherein a material of the patterned oxide layer comprises an oxide having surface hydroxyl groups. ### Claim 10 (depends on 9) The display panel according to claim 9, wherein the oxide comprises at least one selected from thermally evaporated SiOx, ITO, TiO2, and Al2O3. ### Claim 11 (depends on 1) The display panel according to claim 1, further comprising a bottom substrate, opposite to the top substrate, wherein the display layer is disposed between the top substrate and the bottom substrate. ### Claim 12 (depends on 11) The display panel according to claim 11, further comprising a sealant disposed between the top substrate and the bottom substrate and surrounding the display layer. ### Claim 13 (depends on 1) The display panel according to claim 1, wherein a material of the patterned light shielding layer comprises ink material.
