Color conversion filter panel for color organic electroluminescent display and color organic electroluminescent display

摘要

Separating partition walls, demarcating regions forming adjacently color conversion layers having different chromaticities that are stacked and arranged by an inkjet method, have at least one incision in tip faces of both length-direction end portions extended outside the screen region. A color conversion filter panel can be provided having separating partition wall structures which, when forming color conversion layers using an inkjet method, can prevent color mixing of inks between adjacent color conversion layers at length-direction end portions of the separating partition walls.

主权项

1. A color conversion filter panel for configuring a color organic electroluminescent (EL) display in a screen region thereof, comprising:
a transparent substrate; two adjacent color conversion layers, each for a different color and being in a stripe shape, formed on a portion of a surface of the transparent substrate; and a separating partition wall of a stripe shape formed between the two color conversion layers and demarcating the two color conversion layers, both length-direction end portions of the separating partition wall extending to outside the screen region, each of the length-direction end portions having an incision formed on a tip face thereof, the tip face being perpendicular to the surface of the substrate, the incision being enlarged toward inside the screen region to thereby form a cavity.
