Description
基材11は、一方の端部11Z1から他方の端部11Z2までに亘って平面、曲面、平面が連続する形状で構成されている。すなわち、基材11は、第1平板状部11Aと、断面U字状部11Bと、第2平板状部11Cと、を有し、この順にこれらの部位は連続している。基材11は例えばポリイミドで構成される。ただし、この実施形態に限定されず、基材11には他の材質が用いられても良い。
基材支持部12Kは例えばガラスで構成される。基材支持部12Kは、後述するが表示装置10の製造工程にてレーザ80を通過させる必要がある。従って、基材支持部12Kは、少なくともガラス、セラミック、石英のいずれかで構成されれば良く、レーザ80を通過させるその他の材質で構成されても良い。なお、後述する支持基板12の全体としての材質に関しても、前述した基材支持部12Kと同様である。
基材11の第2面J2の炭素濃度は、基材11の第1面J1の炭素濃度に比べて高い。レーザ80が基材11に照射されると、基材11の第2面J2が炭化することになる。レーザ80が照射されていない基材11の第1面J1が炭化していない。その結果、第2面J2は、第1面J1よりも炭素濃度が高い。
回路基板15は、基材11の基材面に沿う方向Xで集積回路14よりも基材11の一方の端部11Z1側に配置される。電子部材50としての集積回路14と回路基板15は、平面視(図4中の上方から見る)で基材支持部12Kに対して重なる。
