DISPLAY PANEL AND DISPLAY DEVICE

摘要

Provided are a display panel and a display device in which light usage efficiency can be improved using a simple structure. A light modulating layer disposed between substrates of a display panel includes a polar solvent, a non-polar solvent, and hydrophilic shape-anisotropic members. The hydrophilic substrate is in contact with the polar solvent and the hydrophobic substrate is in contact with the non-polar solvent. The disposition of the shape-anisotropic hydrophilic members in the light modulating layer is varied by varying the voltage applied to the light modulating layer.

1. A display panel, comprising:
a first substrate on a rear surface side; a second substrate on a display surface side facing the first substrate; and a light modulation layer that is disposed between the first substrate and the second substrate and that controls a degree of reflection of light incident thereon, wherein the light modulation layer includes a polar solvent, a non-polar solvent, and a plurality of shape-anisotropic members having one of hydrophilic, hydrophobic, and amphipathic characteristics, wherein one of the first substrate and the second substrate has the hydrophilic characteristics and is in contact with the polar solvent, wherein another one of the first substrate and the second substrate has the hydrophobic characteristics and is in contact with the non-polar solvent, wherein one of the polar solvent and the non-polar solvent that is in contact with the first substrate has light absorbing characteristics, and wherein a position of the shape-anisotropic members in the light modulation layer is changed by changing a voltage applied to the light modulation layer.
