A luminescent display device comprises a resin substrate having one and another surfaces, an auxiliary electrode made of metal and disposed on the one surface of the resin substrate, a transparent electrode disposed on the auxiliary electrode in a conductive state to the auxiliary electrode, and a luminescent layer composed of an organic compound and disposed on the transparent electrode. These compounds are useful for treating diseases and conditions caused or exacerbated by unregulated p38 MAP Kinase andor TNF activity. Problems of inverse discrete cosine transform mismatch can be eliminated by exactly matching the IDCT function numerical algorithm of the decoder to the IDCT function numerical algorithm used for the decoding portion of the encoder. The anti-collision structure comprises a buffer rod arranged on the piston.
