Abstract: A reflective liquid crystal display device (30) including a reflection electrode (31), a liquid crystal layer (32), and a counter electrode (33) is formed above an insulating layer (25) in a first region (R) of a TFT substrate (20). An organic EL display device (40) including a first electrode (41), an organic layer (43), and a second electrode (44) is formed on the insulating layer (25) of the TFT substrate (20) in a second region (T). A coating layer (45) is formed at least on a surface of the organic EL display device (40) so as to wrap the second electrode (44) and the organic layer (43) of the organic EL display device (40). A part of the coating layer (45) is in contact with the insulating layer (25). As a result, a complex display apparatus capable of preventing the organic layer from deteriorating and excellent in reliability can be obtained.

Abstract: A light modulation layer of a display panel in the present invention includes shape-anisotropic members and liquid crystal molecules. The projected area of the shape-anisotropic members on a first substrate and a second substrate is changed by altering the voltage applied to the light modulation layer, which changes the orientation of the liquid crystal molecules. According to the present invention, it is possible to increase light use efficiency with a simple configuration and to control light/dark switching in both directions at a high switching speed. The present invention is applicable to a television.

Abstract: A display device according to one embodiment of the present invention is provided with a plurality of pixels which are arranged as a matrix on a substrate, and each of which is provided with a liquid crystal display element and an organic EL display element. The organic EL display element is provided with a positive electrode and a negative electrode, which are formed so as to be electrically separated from a pixel electrode and a counter electrode of the liquid crystal display element. Each one of the plurality of pixels is provided with: a first transistor which changes the magnitude of a current to be supplied to the organic EL display element on the basis of the potential of a first bus line; a second transistor which electrically separates the first bus line and the pixel electrode from each other on the basis of the potential of a third bus line; and a third transistor which electrically connects the first transistor and the second transistor with the first bus line on the basis of the potential of a second bus line. A method for driving a display device according to one embodiment of the present invention reduces the potential difference between the pixel electrode and the counter electrode before turning off the second transistor during switching from display by means of the liquid crystal display element to display by means of the organic EL display element.
