The side surface is adjacent to the top surface. The light shielding component has a first part and a second part. The first part is disposed on the top surface of the display panel. The second part is disposed on the side surface of the display panel. The optical film at least covers the border between the top surface of the display panel and the first part of the light shielding component. The width of the first part of the light shielding component is less than 1 mm. ## Claims ### Claim 1 A display device, comprising: a display panel, having a top surface and a side surface adjacent to the top surface; a light shielding component, having a first part and a second part, wherein the first part is disposed on the top surface of the display panel, and the second part is disposed on the side surface of the display panel; and an optical film, at least covering a border between the top surface of the display panel and the first part of the light shielding component, wherein the optical film comprises a first microstructure layer, a second microstructure layer and a main body layer, and the first microstructure layer is disposed between the main body layer and the display panel, the first microstructure layer has a first microstructure area, and the second microstructure layer has a second microstructure area, and an edge of the second microstructure area is closer to an edge of the optical film than an edge of the first microstructure area, wherein a width of the first part of the light shielding component is less than 1 mm. ### Claim 2 (depends on 1) The display device as claimed in claim 1, wherein a material of the light shielding component comprises a metal film, a Mylar film, a metal-containing Mylar film, or a combination thereof. ### Claim 3 (depends on 1) The display device as claimed in claim 1, wherein the optical film completely covers the top surface of the display panel and the first part of the light shielding component. ### Claim 4 (depends on 3) The display device as claimed in claim 3, further comprising: a support member, disposed on a side of the display panel away from the top surface; a back frame, disposed adjacent to the support member; and a fixing mechanism, the support member and the back frame fixed each other by the fixing mechanism. ### Claim 5 (depends on 4) The display device as claimed in claim 4, wherein the support member is a transparent support member. ### Claim 6 (depends on 4) The display device as claimed in claim 4, wherein the second part of the light shielding component is extended to cover the back frame. ### Claim 7 (depends on 4) The display device as claimed in claim 4, wherein the optical film is extended to cover the second part of the light shielding component. ### Claim 8 (depends on 1) The display device as claimed in claim 1, further comprising an adhesive layer, wherein the adhesive layer is disposed between the optical film and the display panel, and a thickness of the adhesive layer is greater than a thickness of the light shielding component. ### Claim 9 (depends on 8) The display device as claimed in claim 8, wherein a top surface of the first part of the light shielding component is substantially coplanar with the top surface of the display panel. ### Claim 10 (depends on 1) The display device as claimed in claim 1, wherein a refractive index of the first microstructure layer is greater than a refractive index of the main body layer, and the refractive index of the main body layer is greater than the refractive index of air. ### Claim 11 (depends on 1) The display device as claimed in claim 1, wherein the main body layer is disposed between the first microstructure layer and the second microstructure layer. ### Claim 12 (depends on 1) The display device as claimed in claim 1, wherein the first microstructure area has a plurality of first prisms. ### Claim 13 (depends on 12) The display device as claimed in claim 12, wherein at least one of the first prisms has a first prism surface and a second prism surface, an angle between the first prism surface and the second prism surface is a first angle. ### Claim 14 (depends on 1) The display device as claimed in claim 1, wherein the second microstructure area has a plurality of second prisms. ### Claim 15 (depends on 14) The display device as claimed in claim 14, wherein at least one of the second prisms has a third prism surface and a fourth prism surface, an angle between the third prism surface and the fourth prism surface is a second angle. ### Claim 16 (depends on 15) The display device as claimed in claim 15, wherein the first microstructure area has a plurality of first prisms, and at least one of the first prisms has a first prism surface and a second prism surface, an angle between the first prism surface and the second prism surface is a first angle, wherein the first angle is substantially the same as the second angle. ### Claim 17 (depends on 1) The display device as claimed in claim 1, further comprising a black matrix disposed at a periphery of the display panel, wherein a width of the black matrix is greater than the width of the first part of the light shielding component.
