An optical film capable of improving luminance of a display unit, in which a viewing angle in the horizontal direction of emitted light of the display unit is wider than a viewing angle in the vertical direction and the emitted light of the display unit has a polarization component in the vertical direction viewable by polarized sunglasses, an illumination system including the same, and a display unit including the same are provided. The optical film includes a plurality of three-dimensional structures extending in one direction and arranged sequentially in a direction crossing the one direction. The three-dimensional structures contain a liquid crystalline polymer having orientation, and have refractive index anisotropy in which refractive index in the extending direction of the three-dimensional structures is smaller than refractive index in the direction crossing the extending direction of the three-dimensional structures.

A protection panel for detecting an X-Y coordinate as an operation position from a potential gradient based on a touch operation to a front substrate is provided. A rear substrate (5) has a first transparent resistive film (5A) and a contact point (5G) connected to a pair of first terminals (5D) through routing circuits (5C) so that the contact point (5G) is arranged in parallel with the first transparent resistive film (5A). When the rear substrate (5) and a front substrate (6) are connected, the contact point (5G) and an expanded region (6Ab) of a second transparent resistive film (6A) on the front substrate (6) form a switch (12) for detecting a contact therebetween, based on a voltage detected in the terminals (6D,5D) of one of the rear substrate (5) and the front substrate (6) when a voltage is applied between the terminals (5D,6D) of the other

A protective panel having touch panel function is used for protecting a front surface of a display device that is disposed so as to be visually recognized from outside, and the protective panel is fitted in a panel fitting part of a casing provided with an opening such that an outer surface of the protective panel forms a flat plane identical with that of the casing with no gap formed therebetween. The protective panel includes: an upper electrode sheet having a decorative layer and upper electrodes provided thereon; and a lower electrode sheet having lower electrodes provided on an upper surface thereof, and the upper electrode sheet and the lower electrode sheet are disposed such that the respective electrodes thereof face with each other. On a lower surface of the upper electrode sheet, at a non-electrode part not provided with the upper electrodes, there is provided a height difference adjustment part that has a thickness substantially equal to each of those of the upper electrodes, and the height difference adjustment part is provided such that short circuit is prevented with the upper electrodes as well as with the lower electrodes.
