Embodiment Construction

[0037] Hereinafter, embodiments of the present invention (hereinafter simply referred to as embodiments) will be described in detail with reference to the accompanying drawings.

[0038] figure 1The configuration of a display device using an organic light emitting element according to an embodiment of the present invention is shown. The display device is used as an ultra-thin organic light-emitting color display device and the like. In this display device, a display region 110 is formed on a substrate 111 . Around the display region 110 on the substrate 111, for example, a signal line driver circuit 120 (which is a driver for image display), a scan line driver circuit 130, and a power supply line driver circuit 140 are formed.

[0039] In the display area 110, a plurality of organic light emitting elements 10 (10R, 10G, and 10B) arranged two-dimensionally in a matrix, and a pixel driving circuit 150 for driving these organic light emitting elements are formed. In the pixel ...

Abstract

The invention relates to a display device and a method of producing the same. The display device includes: a substrate; a plurality of light-emission elements arranged, on the substrate, in a first direction and a second direction intersecting each other, each of the light-emission elements having a first electrode layer, an organic layer including a luminous layer, and a second electrode layer which are laminated in that order; and a separation section disposed, on the substrate, between the light-emission elements adjacent to each other in the first direction, the separation section having two or more pairs of steps. The first electrode layers in the light-emission elements are separated from each other, and the organic layers as well as the second electrode layers in the light-emission elements adjacent to each other in the first direction are separated from each other by the steps included in the separation section.

Description

technical field [0001] The present invention relates to a display device having a self-luminous light-emitting element including an organic layer and a method for manufacturing the same. Background technique [0002] In recent years, an organic EL (electroluminescence, electroluminescence) display using a self-luminous organic light-emitting element including an organic layer has become very practical as a display device replacing a liquid crystal display. The organic EL display is a self-luminous type, so it has a wider viewing angle than a liquid crystal display and the like, and has sufficient responsiveness to a high-definition high-speed image signal. [0003] So far, for organic light-emitting elements, attempts have been made to improve their display performance by introducing a resonator structure and controlling the light generated in the light-emitting layer, such as by improving the color purity of the light-emitting color or increasing the luminous efficiency (fo...
