Description
Technical field
The present invention relates to a kind of display unit and manufacture method thereof, and particularly relate to a kind of organic electroluminescence display device and method of manufacturing same and manufacture method thereof.
Background technology
Flat display apparatus is as liquid crystal indicator (LiquidCrystalDisplayDevice, LCD), plasm display device (PlasmaDisplayPanel, or organic electroluminescence display device and method of manufacturing same (OrganicElectroluminescentDisplay PDP), OLED) CRT display is come compact more in the past, therefore becomes flat display apparatus common now gradually.Wherein, organic electroluminescence display device and method of manufacturing same has more frivolous, deflection, portable, full-color, high brightness, power saving, the advantage such as wide viewing angle and high answer speed.
The OLED display technology of current monochrome has been tending towards ripe, but is considered as the level of flat-panel screens of future generation and its application, and development Full-color OLED is inevitable trend.The current true color technology of OLED has three kinds: 1. full-color required RGB tri-time pixel (subpixel) is reached by independently three elements respectively.2. utilized by Nan dian Yao color conversion layer (colorchangemedium, CCM) to convert RGB color to.3. utilized by white light OLED colored filter (colorfilter) to convert RGB color to.Three kinds of methods respectively have pluses and minuses.The third method utilize white light emitting element to add colored filter is to make Full-color OLED because LCD industry uses the technology of colored filter very ripe, as long as find out the RGB filter of applicable white light OLED, what this technology should be very fast be transferred to OLED uses.And the relatively easy white light OLED of component technology adds that colored filter just becomes the possibility mode reducing Full-color OLED manufacturing cost.
Fig. 1 illustrates a kind of part sectioned view of known organic electroluminescence display device and method of manufacturing same.Organic electroluminescence display device and method of manufacturing same is mainly formed group by organic electroluminescent parts (OLEDassembly) 10 and colorized optical filtering parts (CFassembly) 20, and with sept 30 space distance control between two parts.Organic electroluminescent parts 10 comprise the first substrate 101 with film crystal pipe unit, organic electroluminescence cell 103 is such as be folded in (such as reflecting electrode and through electrode between two electrodes, be not shown in figure), be formed on the first substrate 101 of tool film crystal pipe unit.The method for making of known colorized optical filtering parts 20 is such as form shielding pattern layer 203 as black matrix" (BM) with gold-tinted photoetching process on the glass substrate 201 completing pre-treatment (as cleaning up), form chromatic filter layer 205 again, as gradation forms the color layer of redness (CF-R), green (CF-G) and blue (CF-B); Form cover layer (overcoat, OC) 207 more afterwards, cover chromatic filter layer 205 with whole.Due to red, green not identical with blue color layer thickness, the formation of cover layer 207 can make it reach planarization, and sept 30 can be formed on cover layer 207, organic electroluminescent parts 10 and colorized optical filtering parts 20 are to after group, and sept 30 can maintain the spacing (cellgap) of two parts.But cover layer 207 adds the integral thickness of display unit with the existence of sept 30, the thicker angle that it produces colour cast of display unit is less.In addition, if sept is arranged on by redness, green or one of them color of blue color layer, for arranging sept, must increase the width of the black matrix area of this color, thus the viewing area of this color reduces, and sacrifices the aperture opening ratio of this color.
