[0032] Example of arrangement of display devices
[0033] Figure 1A An example of the arrangement of the display device 1 according to the first embodiment is shown. In this embodiment, the display device 1 is an organic EL display (Organic Electroluminescence Display), and includes a pixel array 2 , a scan signal driver 3 , an information signal driver 4 and a voltage supply unit 5 .
[0034] The pixel array 2 includes a plurality of pixels 211 to 213 arranged in a matrix (to form a plurality of rows and columns). As will be described in detail later, pixel 211 is configured to generate red light, pixel 212 is configured to generate green light, and pixel 213 is configured to generate blue light. Pixels 211, 212 and 213 may also be represented as red, green and blue pixels, respectively. The plurality of pixels 211 to 213 are arranged in three pixels 211 to 213 as a unit. The light-emitting components are combined, and their light amounts are adjusted, thereby emitting li...

[0109] Figure 8 is a schematic cross-sectional view showing a pixel structure ST2 according to the second embodiment. about Figure 8 The respective elements shown in , the same reference numerals as those in the above-described first embodiment denote elements that realize functions similar to those in the first embodiment, and follow the contents of the first embodiment (repetitive description will be omitted) .
[0110] The pixel structure ST2 includes electrode parts 2311 and 2312 provided at positions separated from each other in the vertical direction as the lower electrode 231 , and a plug 2313 electrically connecting them. The first electrode part 2311 is arranged on the substrate 220 , and the second electrode part 2312 is arranged on the plug 2313 above the electrode part 2311 .
[0111] The pixel structure ST2 also includes an optical adjustment layer (hereinafter simply referred to as “adjustment layer”) 281 between the electrode parts 2311 and 2312 in the pixe...

[0121] As a first experimental example based on the above-described first embodiment, a display device 1 (which will be hereinafter referred to as "display device 1 for distinction") was produced through experiments. 1 ”). In the first experimental example, the array form of the pixel array 2 is a stripe array (see Figure 5A ). For each of the lower electrode 231 and the inter-pixel electrode 243, a layer made by stacking a tungsten layer on a titanium nitride layer is used. The lower electrode 231 is formed in an almost square shape of 2.4 [μm]×2.4 [μm]. The distance W12 between the lower electrodes 231 adjacent to each other is 0.2 [μm], which conforms to the minimum processing size. For the insulating layers 241 and 242 forming the insulating member OX11, silicon oxide is used, and the two insulating layers have a thickness of about 30 [nm]. The width W13 of the lower electrode 231 covered by the insulating member OX11 is 0.2 [μm], which corresponds to the minimum proce...
