摘要： An organic electro-luminescence display device emits light by applying a voltage by an image signal between an upper electrode (23) and a lower electrode which sandwich an organic electro-luminescence layer. The organic electro-luminescence layer comprises an electron transporting layer, a light emitting layer, and a hole transporting layer. The electron transporting layer includes an organic material and cesium, and has a moisture absorbing characteristic. A structure in which the same materials as the electron transporting layer are used and which has a different constituent composition and a greater amount of cesium is used as a desiccant (40) and placed in a region which does not overlap the organic electro-luminescence layer, to effectively remove moisture inside the organic electro-luminescence display device.

As means for solving such a task, the present invention provides a display device including a light emitting element and a switching element in a pixel, wherein the switching element is provided for supplying a power source to the light emitting element and is constituted of a first switching element and a second switching element. The first switching element and the second switching element are configured to be operated, in response to inputting of data signals into the inside of the pixel, one switching element assumes a positive bias state and another switching element assumes a reverse bias state, and the bias states are alternately changed over between the first switching element and the second switching element in response to time-sequential inputting of the data signals, and the supply of the power source to the light emitting element is performed by way of either one of the first switching element and the second switching element.
