Abstract: Disclosed herein are a viewing angle control unit, a substrate assembly of the viewing angle control unit, and a display assembly. The viewing angle control unit includes two substrate assemblies, a liquid crystal (LC) component disposed between the substrate assemblies, and a seal component interconnecting the substrate assemblies and surrounding the LC component. At least one of the substrate assemblies includes a transparent base substrate, a transparent electrode layer disposed on the transparent base substrate, and an alignment film disposed on the transparent electrode layer. The transparent electrode layer has a groove extending along at least part of the seal component, so as to mitigate excessive spreading of a material of the alignment film during manufacturing of the viewing angle control unit. The display assembly includes the viewing angle control unit.

Abstract: A display device includes a temperature sensor which is arranged in the inside of a housing, and a control unit which calculates a temperature of a display panel based on an output value of the temperature sensor. The control unit calculates the temperature of the display panel based on a current output value of the temperature sensor and an output value of the temperature sensor received prior to the receiving of the current output value. With such a display device, the temperature of the display panel can be calculated with high accuracy even when a temperature of a device which constitutes a heat source is changed.
