Abstract

The present disclosure relates to an electroluminescent display device having a narrow bezel structure. The electroluminescent display device includes: a substrate; a plurality of pixels; a thin film transistor; a planarization layer; a light emitting diode; a plurality of trenches; a dummy light-emitting layer; a packaging layer and a cover plate. The substrate comprises a display area and a non-display area; the light-emitting diode comprises an anode, a light-emitting layer and a cathode and is arranged on the planarization layer; a plurality of trenches formed at the planarization layer in the non-display area and surrounding the display area; and a dummy light-emitting layer disposed in the non-display area to extend from the light-emitting layer.

Description

technical field [0001] The present disclosure relates to an electroluminescent display device with a narrow bezel structure. In particular, the present disclosure relates to an electroluminescent display device in which a non-display area is formed to have a minimum size to realize an ultra-narrow bezel structure. Background technique [0002] The electroluminescent display device among the display devices adopts a self-luminous system, has excellent viewing angle, contrast ratio, etc., and can reduce weight and thickness, and has advantages in power consumption because a separate backlight is not required. In particular, organic light emitting display (OLED) devices among electroluminescent display devices can be driven by a low DC voltage, have a high response speed, and have low manufacturing costs. In addition, the electroluminescent display device has the advantage of having an ultra-thin structure and utilizing the flexibility of organic materials. [0003] An electr...
