Abstract: To form a sufficiently large storage capacitor, a liquid crystal display device includes a liquid crystal display panel having a first substrate, a second substrate, and a liquid crystal held between the first substrate and the second substrate, the liquid crystal display panel having multiple pixels arranged in matrix. The first substrate has, in a transmissive display area provided in each of the pixels, a laminated structure containing a first transparent electrode, a first insulating film, a second transparent electrode, a second insulating film, and a third transparent electrode which are laminated in this order. The first transparent electrode and the second transparent electrode are electrically insulated from each other and together form a first storage capacitor through the first insulating film, and the second transparent electrode and the third transparent electrode are electrically insulated from each other and together form a second storage capacitor through the second insulating film.

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.

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.
