The light guide plate 24 is a plate member and includes a light entrance surface 24a, an opposite edge surface 24d, and a light exit surface 24b. The light entrance surface 24a is an edge surface of the plate member and opposite the LEDs 22 and light emitted by the LEDs 22 enters the light guide plate 24 through the light entrance surface. The opposite edge surface 24d is another edge surface of the plate member that is on an opposite side from the light entrance surface 24a. The light exit surface 24b is a plate surface of the plate member and the light entering through the light entrance surface 24a exits the light guide plate 24 through the light exit surface. The light reflecting portion 34 is disposed on at least the opposite edge surface 24d and reflecting light travelling within the light guide plate 24 toward the opposite edge surface 24d.

    摘要： A lighting device includes LEDs, a light guide plate, and a frame. The light guide plate includes a light guide plate hole portion passing through in a thickness direction, a light entering surface, and a light exiting surface. The frame surrounds the light guide plate. The frame includes an outer peripheral wall portion and an inner peripheral wall portion. The outer peripheral wall portion opposes an outer peripheral end face of the light guide plate. The inner peripheral wall portion inserted to the light guide plate hole portion opposes an inner peripheral end face of the light guide plate on an inner side of the light guide plate hole portion. The inner peripheral wall portion has a configuration in which the opposing surface has a lower light reflectivity than that of an opposing surface of the outer peripheral wall portion.

    摘要： Provided is a liquid crystal display device in which both a vertical electric field and a horizontal electric field are used and flickering is hardly recognized. The liquid crystal display device includes a liquid crystal panel and a control unit. The control unit includes a horizontal electric field control unit and a vertical electric field control unit. The horizontal electric field control unit controls the potentials of pairs of drive electrodes included in the liquid crystal panel, and thereby controls a horizontal electric field that is generated between each pair of drive electrodes. The vertical electric field control unit controls the potentials of a common electrode and an opposite electrode included in the liquid crystal panel, and thereby controls a vertical electric field that is generated between the common electrode and the opposite electrode. The horizontal electric field control unit controls the intensity and the polarity of the horizontal electric field when the vertical electric field control unit is causing the vertical electric field to be generated. The vertical electric field control unit inverts the polarity of the vertical electric field when the horizontal electric field control unit is maintaining the polarity of the horizontal electric field.
