    • The present invention provides a display device which can realize the easy quality control of a display panel thus enhancing the quality and the reliability of the manufacturing of the display device. To achieve the object, the display device includes a light transmitting glass substrate SUB1 which has a display region AR formed of a pixel circuit in which a large number of display pixels SP each of which is constituted of a light emitting element and an active element are arranged in a matrix array on a main surface thereof; and a sealing glass substrate SUB2 which covers the main surface of the light transmitting glass substrate SUB1 and is hermetically sealed to a peripheral portion of the light transmitting glass substrate SUB1 with a sealing agent SEL therebetween. A dummy pixel DP which is constituted of a light emitting element and a passive element is arranged outside the display region AR on the main surface of the light transmitting glass substrate SUB1. The display pixels SP and the dummy pixel DP are formed by sequentially stacking anodes AD, organic multilayered films ELM and cathodes KD on the main surface of the light transmitting glass substrate SUB1 respectively. In the dummy pixel DP, the organic multilayered film ELM is exposed by removing at least a portion of the cathode KD, and an electric current path is formed between a remaining other portion of the cathode KD and the anode AD.

    • Inside surround desiccant pattern A surrounding an organic EL element by bonding an element substrate to a sealing board, outside surround desiccant pattern C surrounding the inside surround desiccant pattern A, and internal desiccant pattern (having a thinner film thickness than the inside surround desiccant pattern A) surrounded by the inside surround desiccant pattern A are formed on the sealing board by one time screen printing. For this purpose, a screen mask is utilized on which opening patterns for the inside and outside surround desiccant patterns A, C and an opening pattern having a narrower opening width than the opening patterns for A and C for forming an internal desiccant pattern are formed. With this configuration, it has been achieved to manufacture a highly reliable organic EL display apparatus in more simplified process.
