Abstract
An optical path control member according to an embodiment includes: a lower substrate; the lower electrode is arranged on the upper surface of the lower substrate; the upper substrate is arranged on the lower substrate; the upper electrode is arranged on the lower surface of the upper substrate; a light conversion unit disposed between the lower electrode and the upper electrode; and an adhesive layer provided between the light conversion unit and the upper electrode, in which the light conversion unit includes partition wall portions and accommodating portions that are alternately disposed, the accommodating portions having a light transmittance that varies according to application of a voltage, and when a ratio (thickness / dielectric constant) of a thickness of the accommodating portions to a dielectric constant thereof is defined as A, A is a positive integer greater than or equal to 2; when the ratio (thickness / dielectric constant) of the thickness of the adhesive layer to the dielectric constant thereof is defined as B, the value of A is greater than the value of B.
Description
technical field [0001] Embodiments provide an optical path control member having improved driving characteristics by controlling the thickness and dielectric constant of an adhesive layer between a pattern layer and an electrode layer. Background technique [0002] The light-shielding film shields transmission of light from a light source, and is attached to the front surface of a display panel (which is a display device for a mobile phone, a notebook computer, a tablet computer, a car navigation device, a vehicle touch screen, etc.) The incident angle adjusts the viewing angle of the light to present a clear image quality at the viewing angle required by the user when the display transmits the picture. [0003] In addition, the light-shielding film may be used for windows of vehicles, buildings, etc., to partially shield external light, thereby preventing glare or preventing the inside from being seen from the outside. [0004] That is, the light-shielding film can control...
