Abstract: In the present embodiment, a sealing agent (50) sealing two substates contains a low melting-point glass material and is adhered to each of a first substrate (10) and a second substrate (20), a barrier rib (60), which is formed in such a manner as to surround the outer periphery of an electronic element (30), is disposed between the sealing agent (50) and the electronic element (30), and between the first substrate (10) and the second substrate (20), and the sealing agent (50) is spaced apart from the barrier rib (60). As a result, a deterioration of the electronic element, caused by the heat produced when sealing, may be prevented while the electronic element formed between the two substrates is protected from moisture and oxygen.

Abstract: A liquid crystal cell includes a color filter substrate, an array substrate, a liquid crystal layer, and two alignment control layers. The color filter substrate includes a color conversion layer for converting color of light but not include an alignment film containing polyamic acid or polyamide. The array substrate is opposed to the color filter substrate. The alignment control layers are formed on an inner surface of the color filter substrate and an inner surface of the array substrate, respectively. The alignment control layers contact the liquid crystal layer. The alignment control layers are made of reactants of radical polymerizable monomers added to a liquid crystal material for forming the liquid crystal layer. The alignment control layers control orientations of liquid crystal molecules in the liquid crystal layer. The radical polymerizable monomers include radical polymerizable monomers having ultraviolet-ray absorbing functional groups.

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.
