An organic light emitting display device includes: a substrate including: pixel regions; connection regions between adjacent pixel regions from among the pixel regions, respectively; and a region having a through-opening, the region being defined by the adjacent pixel regions, and the connection regions respectively between the adjacent pixel regions; a sub-pixel structure on the substrate at each of the pixel regions; and an organic pattern on a side wall of the substrate, the side wall being adjacent to the through-opening.

An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.
