The invention provides a circuit section of a TFT layer disposed behind an adjacent EL display device, so that a gap defined between pixels at peripheries of the adjacent EL display devices may be 10 m. The blue phosphorescent compound can emit deep blue light and can improve color purity and reduce power consumption when used in an organic electroluminescent device. The inner tube is sized to fit telescopically within the outer tube. There are a plurality of flanges or ears extending at the proximal end of the proximal portion.
