Liquid crystal display device
The present invention provides a liquid crystal display device with a narrow picture frame which reduces a sealing defect by suppressing spreading of an orientation film. In a region inside a sealing material and outside a display region, an uneven surface for suppressing spreading of the orientation film is formed. It is preferable that the uneven surface is formed using an insulation film and, at the same time, an etching stopper layer is formed below the insulation film which forms the uneven surface. It is more preferable that the uneven surface and the stopper layer are simultaneously formed with a layer used for forming pixels in a step for forming such a layer thus preventing the increase of manufacturing steps.
