A　Flexible　Liquid　Crystal　Micro-Lens　Arrays　(LC　MLAs)　with　an　adjustable　focal　length　was　designed　and　prepared　to　solve　the　narrow　viewing　angle　of　the　integrated　imaging.　In　this　paper,　the　hole-patterned　driven-　electrode　arrays　were　fabricated　by　a　photolithography　technology　and　the　flexible　Polyimide　(PI)　film　was　prepared　by　a　spin　coating　method　on　the　flexible　ITO　glass　substrate.　After　the　PI　film　layer　was　heated　at　60°C　for　5　min,　the　PI　orientation　layer　was　formed　by　using　the　plasma　at　a　power　of　630　W　for　5　minutes.　The　optical　properties　of　LC　MLAs　with　a　flat　substrate　and　a　curvature　radius　of　7.5cm　were　studied　after　the　LC　MLAs　were　fabricated.　The　experimental　results　show　that　the　prepared　LC　MLAs　can　achieve　the　excellent　focusing　properties　under　the　condition　of　a　flat　plate　and　a　curvature　radius　of　7.5　cm.　The　interference　patterns　are　uniform　and　the　focal　radius　are　small　when　the　operating　voltages　are　applied　to　the　LC　MLAs.　Further,　the　focal　length　of　the　flexible　LC　MLAs　with　the　curvature　radius　of　7.5　cm　can　be　tunable　from　0.43　mm　to　1.05　mm　when　the　operating　voltages　are　changed　from　3　Vrms　to　5.3　Vrms.　©　2021,　Science　Press.　All　right　reserved.
