a display panel provided on the rear surface of the cover glass so as to have a plurality of layers; a cut-out region formed on at least one of the plurality of layers; a side optical shield film provided on the side surface of the at least one layer exposed to the outside by the cut-out region; and a front optical shield film provided to one region adjacent to the cut-out region of the cover glass. ## Claims ### Claim 1 A mobile terminal comprising: a cover glass; a display panel disposed on a rear surface of the cover glass to form a plurality of layers; a cut-out region defined in at least one of the plurality of layers; a side surface optical shielding film disposed on a side surface of the at least one layer exposed to the outside by the cut-out region; and a front surface optical shielding film disposed in a region adjacent to the cut-out region of the cover glass. ### Claim 2 (depends on 1) The mobile terminal of claim 1, wherein the display panel is a liquid crystal display (LCD) including a liquid crystal layer, wherein the cut-out region is defined in all of the plurality of layers except for the liquid crystal layer, wherein the mobile terminal further includes an auxiliary optical shielding film disposed in a region adjacent to the cut-out region of the liquid crystal layer. ### Claim 3 (depends on 1) The mobile terminal of claim 1, further comprising: an optical sensor disposed inside the cut-out region or at the rear of the cut-out region. ### Claim 4 (depends on 3) The mobile terminal of claim 3, wherein the optical sensor includes a camera sensor, wherein the camera sensor includes: a lens barrel; and an image sensor, wherein the lens barrel is disposed inside the cut-out region, and the image sensor is located at the rear of the cut-out region. ### Claim 5 (depends on 4) The mobile terminal of claim 4, wherein a backlight unit layer is disposed at a rearmost portion of the display panel, wherein the image sensor is joined to a region adjacent to the cut-out region of a rear surface of the backlight unit layer. ### Claim 6 (depends on 3) The mobile terminal of claim 3, wherein the display panel includes organic light emitting diodes (OLEDs), wherein a rearmost layer of the display panel is a cushion tape layer, wherein the cushion tape layer is formed wider than the cut-out region to form a seating region of the optical sensor. ### Claim 7 (depends on 1) The mobile terminal of claim 1, wherein the cut-out region forms a step having a cross-section area increasing forwardly. ### Claim 8 (depends on 7) The mobile terminal of claim 7, wherein the side surface optical shielding film contains black ink, and is applied to the side surface in a spraying scheme.
