PROBLEM TO BE SOLVED: To improve reading accuracy of a cutting reading mark m.SOLUTION: A manufacturing method of a display device 100 includes the steps of: setting a circular polarization plate 48 where a notch n is formed on a display surface side F of a display area A of a flexible substrate 10 so that the notch n is superimposed on a cutting reading mark m; reading the cutting reading mark m via the notch n by use of an optical device X; determining cutting lines C1 to C3 for cutting a reverse reinforcement film 58 to a size corresponding to an outer shape of a frame rim area B on the basis of the read cutting reading mark m; and cutting the reverse reinforcement film 58 along the cutting lines C1 to C3.SELECTED DRAWING: Figure 1 【課題】切断用読み取りマークｍの読み取り精度を向上する。【解決手段】表示装置１００の製造方法において、フレキシブル基板１０の表示領域Ａの表示面側Ｆに、切り欠きｎが形成される円偏光板４８を、切り欠きｎが切断用読み取りマークｍに重なるように設ける工程と、光学装置Ｘを用いて、切り欠きｎを介して切断用読み取りマークｍを読み取る工程と、読み取った切断用読み取りマークｍに基づいて、額縁領域Ｂの外形に対応する大きさに裏補強フィルム５８を切断するための切断線Ｃ１〜Ｃ３を決定し、切断線Ｃ１〜Ｃ３に沿って裏補強フィルム５８を切断する工程と、を含む。【選択図】図１
