Please also note that the present invention is not limited to the above-mentioned adjustment method, and the visual design needs to adjust the size of each pixel area PX. The display device 300 of the present embodiment is similar to the above-described first preferred embodiment except for the difference in aperture ratio of the pixel region PX, and thus will not be described herein.

請參考第7圖至第9圖。第7圖繪示了本發明之第四較佳實施例之顯示裝置的示意圖。第8圖繪示了本實施例之顯示裝置的畫素區之上視示意圖。第9圖繪示了本發明之另一較佳實施例之顯示裝置的畫素區之上視示意圖。如第7圖所示,本實施例之顯示裝置400與上述第一較佳實施例的不同處在於,顯示裝置400更包括圖案化遮光層BM設置於基板110以及光致發光層130之間,用以於至少部分之畫素區PX中定義出複數個開口區AR,且至少部分之開口區AR係彼此尺寸大小相異。舉例來說,當第一次畫素區P1、第二次畫素區P2以及第三次畫素區P3分別用以呈現紅光、綠光以及藍光時,若考量各次畫素區之間發光效率差異而造成不均勻的狀況,且圖案化阻擋層120於基板110上所定義出各畫素區PX之開口率係實質相同,則可利用圖案化遮光層BM於至少部分之畫素區PX中定義出尺寸大小不同之開口區AR以補償發光效率差異而造成不均勻的狀況。如第7圖所示,圖案化遮光層BM可分別於第二次畫素 區P2以及第三次畫素區P3內定義出第二開口區AR2以及第三開口區AR3,而第一次畫素區P1中可不設置圖案化遮光層BM而僅以圖案化阻擋層120定義出第一開口區AR1。換句話說,圖案化遮光層BM可僅設置於第二次畫素區P2與第三次畫素區P3中,但並不以此為限。藉由調整各開口區AR的面積大小,例如可將第一開口區AR1之面積控制在最大,第二開口區AR2之面積次之,而第三開口區AR3之面積控制在最小的狀況下,可利用此開口率的差異來補償各畫素區PX之間發光效率不同而造成之不均勻狀況。另請注意,本發明並不以上述之調整方式為限而可視設計需要對各畫素區PX之開口區AR大小進行調整。本實施例之顯示裝置400除了圖案化遮光層BM以及開口區AR的大小差異之外,其餘各部件之設置、材料特性以及發光方式與上述第一較佳實施例相似,故在此並不再贅述。值得說明的是,圖案化遮光層BM之光學密度(optical density,OD)較佳係大於3.5,以達到所需之遮光效果。Please refer to Figures 7 to 9. Figure 7 is a schematic view showing a display device of a fourth preferred embodiment of the present invention. FIG. 8 is a top plan view showing a pixel area of the display device of the embodiment. FIG. 9 is a top plan view showing a pixel area of a display device according to another preferred embodiment of the present invention. As shown in FIG. 7, the display device 400 of the present embodiment is different from the first preferred embodiment in that the display device 400 further includes a patterned light shielding layer BM disposed between the substrate 110 and the photoluminescent layer 130. A plurality of open areas AR are defined in at least a portion of the pixel regions PX, and at least a portion of the open areas AR are different in size from each other. For example, when the first pixel region P1, the second pixel region P2, and the third pixel region P3 are used to represent red, green, and blue light, respectively, if each pixel region is considered The difference in luminous efficiency causes unevenness, and the aperture ratio of the pixel region PX defined by the patterned barrier layer 120 on the substrate 110 is substantially the same, and the patterned light shielding layer BM can be utilized in at least a portion of the pixel region. The open area AR having different sizes is defined in the PX to compensate for the unevenness of the luminous efficiency. As shown in FIG. 7, the patterned light shielding layer BM can be respectively in the second pixel The second opening area AR2 and the third opening area AR3 are defined in the area P2 and the third pixel area P3, and the patterned light shielding layer BM may not be disposed in the first pixel area P1 but only defined by the patterned barrier layer 120. The first open area AR1 is exited. In other words, the patterned light shielding layer BM may be disposed only in the second pixel region P2 and the third pixel region P3, but is not limited thereto. By adjusting the size of each open area AR, for example, the area of the first open area AR1 can be controlled to the maximum, the area of the second open area AR2 is second, and the area of the third open area AR3 is controlled to be the minimum. This difference in aperture ratio can be utilized to compensate for the unevenness caused by the difference in luminous efficiency between the pixel regions PX. Please also note that the present invention is not limited to the above-mentioned adjustment method, and the visual design needs to adjust the size of the open area AR of each pixel area PX. In addition to the difference in size between the patterned light shielding layer BM and the opening area AR, the display device 400 of the present embodiment has similar settings, material characteristics, and illumination modes to those of the first preferred embodiment described above, and thus is no longer Narration. It should be noted that the optical density (OD) of the patterned light-shielding layer BM is preferably greater than 3.5 to achieve the desired light-shielding effect.

如第7圖與第8圖所示,本實施例之各開畫素區PX與各開口區AR較佳可分別為矩形形狀,但本發明並不以此為限。在本發明之其他較佳實施例中亦可視需要使用其他適合形狀之畫素區PX與開口區AR。舉例來說,如第9圖所示,本發明之另一較佳實施例中,各開畫素區PX與各開口區AR亦可分別為圓形形狀。As shown in FIG. 7 and FIG. 8 , each of the open pixel regions PX and the respective open regions AR of the present embodiment may preferably have a rectangular shape, but the invention is not limited thereto. In other preferred embodiments of the present invention, other suitable shape pixel regions PX and open regions AR may be used as needed. For example, as shown in FIG. 9, in another preferred embodiment of the present invention, each of the open pixel regions PX and each of the open regions AR may also have a circular shape.

請參考第10圖。第10圖繪示了本發明之第五較佳實施例之顯示裝置500的示意圖。如第10圖所示,本實施例之顯示裝置500 與上述第四較佳實施例的不同處在於,圖案化遮光層BM係部分設置於圖案化阻擋層120以及基板110之間。換句話說,圖案化遮光層BM可先形成於基板110上,而於圖案化遮光層BM形成之後再形成圖案化阻擋層120。本實施例之顯示裝置500除了圖案化遮光層BM的設置位置之外,其餘各部件之設置、材料特性以及發光方式與上述第四較佳實施例相似,故在此並不再贅述。Please refer to Figure 10. FIG. 10 is a schematic view showing a display device 500 according to a fifth preferred embodiment of the present invention. As shown in FIG. 10, the display device 500 of this embodiment The difference from the fourth preferred embodiment is that the patterned light shielding layer BM is partially disposed between the patterned barrier layer 120 and the substrate 110. In other words, the patterned light shielding layer BM may be formed on the substrate 110 first, and then the patterned barrier layer 120 is formed after the patterned light shielding layer BM is formed. The display device 500 of the present embodiment is similar to the above-described fourth preferred embodiment except for the arrangement position of the patterned light shielding layer BM, and thus will not be described herein.

綜上所述,本發明之顯示裝置係利用單一種類的發光二極體設置於各畫素區中,藉由發光二極體所產生之短波長光線激發不同顏色之光致發光層以呈現出顯示效果,故可簡化相關製程、降低生產成本以及提升顯示效果。In summary, the display device of the present invention uses a single type of light-emitting diode to be disposed in each pixel region, and the short-wavelength light generated by the light-emitting diode excites the photoluminescent layer of different colors to present The effect is displayed, so the related processes can be simplified, the production cost can be reduced, and the display effect can be improved.
