An organic electroluminescence display device is disclosed wherein plural organic electroluminescence elements each having an anode, a cathode and an organic layer sandwiched in between the anode and the cathode, the plural organic electroluminescence elements including organic electroluminescence elements developing different colors in a row direction, and at least one of the organic layers having an outer edge of a conic section at an end portion in a column direction thereof, the outer edge of the conic section becoming narrower gradually in its width in a row direction of vapor deposition thereof toward an extreme end at an end portion in a column direction thereof. The organic electroluminescence display device can improve the vapor deposition accuracy and the degree of design freedom.
