PURPOSE: A display optical filter for increasing the quantity of light is provided to minimize the thickness of the display device by performing electromagnetic wave shield function and improving visibility. CONSTITUTION: A display optical filter includes a cutting and shielding layer(60). The cutting and shielding layer extracts pattern forming condition for preventing moire and ghost image. A stripe type cut off and shield are repeatedly formed the stripe type cut off and shield are separated per the constant interval. The bridge cut off and shielding unit is repeatedly formed the bridge cut off in which they are adjacent among the stripe type cut off and shield stripe type. The height ratio of the separation distance with the bridge cut off and the adjacent shield and bridge cut off and shield are 1:0.3 or 1:0.6.
