Embodiment Construction

[0064] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0065] figure 1 is a schematic plan view of a pixel of the OLED device according to the first embodiment of the present invention.

[0066] Such as figure 1 As shown, in ( figure 2 In the OLED device 100, the pixel P includes a red pixel region R-SP, a white pixel region W-SP, a blue pixel region B-SP and a green pixel region G-SP. Each of the pixel areas R-SP, W-SP, B-SP, and G-SP includes a light emitting area EA and a non-light emitting area NEA along an edge of the light emitting area EA. That is, the non-light emitting area NEA is disposed on the outer periphery of the light emitting area EA. The bank 119 is disposed on the non-light emitting area NEA. That is, the banks 119 are disposed at boundaries of the respective pixel regions R-SP, W-SP, B-SP, and G-SP.

[0067] exist figure 1 , the pixel regions R-SP, W-SP, B-SP, an...

Abstract

Organic light emitting diode display device. An organic light emitting display device includes a substrate including a white pixel region, a blue color filter pattern in a first region of the white pixel region, an overcoat layer covering the blue color filer pattern and including a micro-lens, a first electrode on the overcoat layer, an organic emitting layer covering the first electrode, and a second electrode covering the organic emitting layer.

Description

technical field [0001] Embodiments of the present invention relate to organic light emitting display devices, and more particularly, to organic light emitting display devices having improved light outcoupling efficiency) and improved color temperature. Background technique [0002] With the development of information technology and mobile communication technology, display devices capable of displaying visual images have also been developed. [0003] Flat panel display devices (such as liquid crystal display (LCD), plasma display panel (PDP) devices, field emission display (FED) devices, electroluminescence display devices (ELD), organic light emitting display (OLED) devices, etc.) and other advantages have been developed and used instead of cathode ray tubes. [0004] Among flat panel display devices, an OLED device, which is a self-luminous type, does not require a backlight unit in an LCD device, and has excellent characteristics of thin profile and light weight. In addi...
