Problems solved by technology

However, since the first distance d1 does not decrease in the vacuum thermal evaporation method, the size of the dead area does not decrease without the shadow effect, and the size of the organic pattern 60 is reduced for higher resolution. Small

Embodiment Construction

[0029] Reference will now be made in detail to various embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, like drawings will be used to refer to the same or like parts.

[0030] image 3 is a cross-sectional view showing the organic electroluminescence display device according to the first embodiment of the present invention.

[0031] exist image 3In this example, a bottom emission type organic electroluminescent display (ELD) device 100 includes first and second substrates 101 and 103 which are spaced apart from each other. The first and second substrates 101 and 103 are attached to each other and sealed with a seal pattern 120 at a boundary portion. In addition, the first and second substrates 101 and 103 include a plurality of pixel regions P each including first, second and third sub-pixel regions SP1, SP2 and SP3. For example, the first, second and third sub-pixel regions SP1, SP2 and SP3 may correspond to...

Abstract

An organic electroluminescent display device includes: first and second substrates facing and spaced apart from each other, the first and second substrates including at least one pixel region having first, second and third sub-pixel region; a gate line and a data line on the first substrate, the gate line and the data line crossing each other to define the at least one pixel region; a first electrode on the first substrate in each of the first, second and third sub-pixel regions; first, second and third organic patterns on the first electrode in the first, second and third sub-pixel regions, respectively, the first, second and third organic patterns having a zigzag shape along a first direction parallel to the gate line with respect to a virtual line passing through a central portion of each of the first, second and third sub-pixel regions; and a second electrode on the first, second and third organic patterns.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2010-0027330 filed on Mar. 26, 2010, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to an organic electroluminescence display (ELD) device, in particular to an organic electroluminescence display device with improved aperture ratio and resolution through the arrangement of organic patterns in sub-pixel regions, and an organic electroluminescence display device A method of manufacturing such an organic ELD device. Background technique [0003] Although cathode ray tubes (CRTs) are widely used as display devices, devices such as plasma display panel (PDP) devices, liquid crystal display (LCD) devices, and organic electroluminescence displays (ELD) called organic light emitting diode (OLED) devices ) devices such as flat panel displays (FPDs) have been the subject of recent research and development. [0004] Among various FPD devices,...
