A light emission device manufactured by a method of forming a curved surface having a radius of curvature to the upper end of an insulator 19, exposing a portion of the first electrode 18c to form an inclined surface in accordance with the curved surface, and applying etching so as to expose the first electrode 18b in a region to form a light emission region, in which emitted light from the layer containing the organic compound 20 is reflected on the inclined surface of the first electrode 18c to increase the total take-out amount of light in the direction of an arrow shown in FIG. 1A and, further, forming a light absorbing multi-layered film 24 comprising light absorbing multi-layered film on the first electrode 18c other than the region to form the light emission region, thereby obtaining a light emission device of a structure increasing the amount of light emission taken out in one direction in a light emission element, while not all the light formed in the layer containing the organic compound are taken out from the cathode as a transparent electrode toward TFT but the light was emitted also, for example, in the lateral direction (direction parallel with the plane of the substrate).

Disclosed is a display apparatus. The display apparatus includes: a display module including a flexible substrate, a display panel, and an encapsulation film; a lower module disposed below the display module; an upper module disposed on the display module; and an elasticity-adjusting layer disposed on or below the display module to adjust a position of a neutral plane in bending of the display apparatus, wherein an elastic modulus of the elasticity-adjusting layer is less than that of at least one of the display module, the lower module, or the upper module, so as to position the neutral plane within or proximate to the display module.

A pixel structure of electroluminescent display panel has a first sub-pixel region, a second sub-pixel region, and a third sub-pixel region. The pixel structure of electroluminescent display panel includes a first organic light-emitting layer, and a second organic light-emitting layer. The first organic light-emitting layer is disposed in the first sub-pixel region for generating a first primary color light in the first sub-pixel region. The second organic light-emitting layer is disposed in the second sub-pixel region, and the third sub-pixel region for generating a second primary color light in the second sub-pixel region, and for generating a third primary color light in the third sub-pixel region. The first sub-pixel region, the second sub-pixel region, and the third sub-pixel region have different cavity lengths.
