Liquid crystal display device

Abstract

The present invention suppresses the spreading by wetting of an orientation film of a liquid crystal display panel outside a display region and, at the same time, maintains the uniformity of film thickness of the orientation film within a display region. In a liquid crystal display device which includes a display panel which arranges a sealing material having an annular shape between a pair of substrates, seals a liquid crystal material in a space surrounded by the pair of substrates and the sealing material, the pair of substrates form orientation films on surfaces thereof opposite to surfaces thereof which face each other, the orientation films are brought into contact with transparent electrodes which are formed on surfaces of transparent substrates by way of insulation layers, at least one substrate out of the pair of substrates includes an elongated groove portion which extends in the direction along an outer periphery of the display region in a substantially annular region which is arranged inside a region where the sealing material is arranged and outside the display region, and the groove portion is formed of recessed grooves which are formed in the insulation layer and an ITO film which extends along side surfaces and bottom surfaces of the recessed grooves.
