    Abstract: A filling material is provided in an interval part between a first substrate provided with a light emitting device in a pixel and a second substrate provided with a color filter layer corresponding to each pixel which is provided to face each other and a protruding part is provided in the interval part. The protruding part is provided separated along one edge of each pixel. An end part in a length direction of the protruding part is formed in a cone or streamlined shape. In addition, the protruding part is formed from a material having light absorbing properties such as carbon black so as to provide light shielding properties. By adopting this structure, it is possible to solve a problem of mixing colors produced between pixels. It is possible to ensure that the flow of the filling material provided between the first substrate and the second substrate is not obstructed.

    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.

    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.
