  • Publication number: 20140061624
    Abstract: A space between a lower substrate and an upper substrate including an organic EL light-emitting layer which includes a display region for displaying an image is filled by a dam material which is applied to enclose an exterior edge of the display region and a filling material which is dripped into the interior side of the dam material. The dam material is an epoxy resin with a comparatively high viscosity before hardening and the filling material is an epoxy resin with a comparatively low viscosity before hardening. A substrate concave part is formed between the display region on a surface of the lower substrate and a coating region of the dam material.

  • Publication number: 20120327322
    Abstract: A column for defining the interval between a TFT substrate and an opposed substrate is formed at a crossing point between a drain line and a scanning line. At the crossing point where the column is formed, the drain line is formed to have a wider width to prevent light leakage. Further, at the crossing point where the column is formed, the scanning line is formed to have a narrower width to prevent increase of capacitance between the drain line and the scanning line. The column is formed at a crossing point corresponding to a specific color, e.g., a blue pixel B, so that a difference in transmittance and in characteristic of thin film transistors due to formation of the column is initially compensated.
